Step-by-step solution for: Balanced and Unbalanced Forces Worksheet GG Interactive Worksheet ...
Let's solve each question on the "Balanced & Unbalanced Forces" worksheet step by step and explain the reasoning behind each answer.
---
Answer:
All forces have:
- Magnitude (size)
- Direction
Explanation:
A force is a vector quantity, meaning it has both size (how strong it is) and direction (which way it’s pushing or pulling).
---
Answer:
b. balanced
Explanation:
If neither team moves, it means the forces from both sides are equal in magnitude but opposite in direction — they cancel out. This is called balanced forces, resulting in no motion.
---
Answer:
The forces are unbalanced — one team is applying a greater force than the other.
Explanation:
When there is motion, it indicates an unbalanced force. The team with the stronger pull wins because their force exceeds the opposing force.
---
Force pulling down: Gravity
Force pushing up: Air pressure / Upward force from air stream
Explanation:
The ball floats because the upward force from the air stream balances the downward force of gravity. These two forces are equal and opposite, so the ball stays suspended.
---
Answer:
The ping-pong ball would move upward or be pushed higher because the upward force becomes greater than the downward force of gravity.
Explanation:
At full power, the air stream exerts a larger upward force. Since this now exceeds the downward gravitational force, the net force is upward → causing acceleration upward.
---
Answer:
c. direction of force
Explanation:
To return to his starting point, Dr. Jeff must reverse the direction of the force from the fire extinguisher. Newton’s Third Law: for every action, there's an equal and opposite reaction. Changing the direction of thrust changes the direction of motion.
---
Answer:
True
Explanation:
For a hoverboard to float (remain stationary in the air), the upward lift force must balance the downward force of gravity. Balanced forces mean no net movement — so yes, balanced forces are essential for stable floating.
---
Answer:
1. Gravity (pulling down)
2. Normal force (from the surface pushing up)
Explanation:
Before the egg is dropped, it rests on a surface. Gravity pulls it down, but the surface pushes up with an equal and opposite force (normal force). These balanced forces keep the egg at rest.
---
Answer:
True
Explanation:
Once the egg is released (or the support is removed), the upward normal force disappears. Only gravity acts — making the net force downward. This unbalanced force causes the egg to accelerate downward.
---
Answer:
Because the force may not have been strong enough, or other forces like friction or air resistance slowed it down, or the angle/direction wasn't precise.
Alternative explanation (depending on context):
It could also be due to an unbalanced force acting against it, such as friction between the ball and the ground, or the ball hitting a slope or obstacle.
More complete answer:
Even though the initial force moved the ball in the right direction, friction and air resistance reduced its speed over time. Also, if the force wasn’t applied with enough strength or correct direction, the ball might not have reached the hole. So, other forces or insufficient force magnitude prevented it from going in.

1. What 2 things do all forces have?
Answer:
All forces have:
- Magnitude (size)
- Direction
Explanation:
A force is a vector quantity, meaning it has both size (how strong it is) and direction (which way it’s pushing or pulling).
---
2. When playing tug of war and neither side moves, forces are…
Answer:
b. balanced
Explanation:
If neither team moves, it means the forces from both sides are equal in magnitude but opposite in direction — they cancel out. This is called balanced forces, resulting in no motion.
---
3. In tug of war, when one team moves toward the other, what can be said about the forces?
Answer:
The forces are unbalanced — one team is applying a greater force than the other.
Explanation:
When there is motion, it indicates an unbalanced force. The team with the stronger pull wins because their force exceeds the opposing force.
---
4. When floating a ping-pong ball with a hairdryer, which two forces are balanced?
Force pulling down: Gravity
Force pushing up: Air pressure / Upward force from air stream
Explanation:
The ball floats because the upward force from the air stream balances the downward force of gravity. These two forces are equal and opposite, so the ball stays suspended.
---
5. If the hairdryer was put on full power, what would happen? Why?
Answer:
The ping-pong ball would move upward or be pushed higher because the upward force becomes greater than the downward force of gravity.
Explanation:
At full power, the air stream exerts a larger upward force. Since this now exceeds the downward gravitational force, the net force is upward → causing acceleration upward.
---
6. When Dr. Jeff jumps on a skateboard and uses the fire extinguisher to move, which of these does he change to move BACK to where he started?
Answer:
c. direction of force
Explanation:
To return to his starting point, Dr. Jeff must reverse the direction of the force from the fire extinguisher. Newton’s Third Law: for every action, there's an equal and opposite reaction. Changing the direction of thrust changes the direction of motion.
---
7. True or false: balanced forces are important for a hover board to float.
Answer:
True
Explanation:
For a hoverboard to float (remain stationary in the air), the upward lift force must balance the downward force of gravity. Balanced forces mean no net movement — so yes, balanced forces are essential for stable floating.
---
8. In Zoe’s egg drop experiment, which two forces are balanced that keep the egg from moving before she hits the pan?
Answer:
1. Gravity (pulling down)
2. Normal force (from the surface pushing up)
Explanation:
Before the egg is dropped, it rests on a surface. Gravity pulls it down, but the surface pushes up with an equal and opposite force (normal force). These balanced forces keep the egg at rest.
---
9. True or false: the downward motion of the egg in Zoe’s experiment is due to unbalanced forces.
Answer:
True
Explanation:
Once the egg is released (or the support is removed), the upward normal force disappears. Only gravity acts — making the net force downward. This unbalanced force causes the egg to accelerate downward.
---
10. When Izzy applied a force to the golf ball, it went in the right direction, so why didn’t it go in the hole?
Answer:
Because the force may not have been strong enough, or other forces like friction or air resistance slowed it down, or the angle/direction wasn't precise.
Alternative explanation (depending on context):
It could also be due to an unbalanced force acting against it, such as friction between the ball and the ground, or the ball hitting a slope or obstacle.
More complete answer:
Even though the initial force moved the ball in the right direction, friction and air resistance reduced its speed over time. Also, if the force wasn’t applied with enough strength or correct direction, the ball might not have reached the hole. So, other forces or insufficient force magnitude prevented it from going in.
