Step-by-step solution for: Motion and Stability Quiz Worksheets
Let's go through each statement in the Force and Motion Quiz and determine whether it is True or False, followed by a brief explanation for each.
---
✔ True
- Balanced forces mean equal forces in opposite directions. This results in no net force, so the object will either stay at rest or continue moving at constant velocity (no acceleration).
---
✘ False
- Gravity is an attractive force that pulls objects toward the Earth, not pushes them away.
---
✔ True
- This is the basic definition of a force: any interaction that can cause an object to accelerate. It can be a push or a pull.
---
✘ False (with nuance)
- A net force in the direction of motion can make an object speed up, but force can also slow down or change direction. So this statement is too general.
- Better answer: False — because force doesn’t *always* make things move faster (e.g., friction slows things down).
- So: ✘ False
---
✘ False
- Friction is not always helpful. For example, it causes wear on machine parts and reduces efficiency. But it’s useful for walking or stopping cars. So it depends.
---
✔ True
- Balanced forces result in zero net force, so no acceleration. That means no change in speed or direction. The object maintains its current motion.
---
✘ False
- The amount of space between two points is distance.
- Position refers to where an object is located relative to a reference point.
---
✔ True
- All forces are either pushes or pulls. If a force acts on an object, it could be due to a push or pull, causing motion.
---
✔ True
- Motion is a change in position over time. A swing clearly changes position, so yes, it’s motion.
---
✔ True
- Newton’s First Law: A force causes acceleration (change in motion), including speeding up, slowing down, or changing direction.
---
✘ False
- That force is gravity, not friction. Friction opposes motion between surfaces.
---
✔ True
- Formula: Speed = Distance / Time — correct.
---
✘ False
- Temperature measures heat, not distance. Distance is measured with rulers, meters, etc.
---
✔ True
- In tug of war, if one side pulls harder (unbalanced force), the rope moves toward that side, and the other team loses.
---
✘ False
- This is confusingly worded. Motion is the result of movement. To move an object, you need a force, not "motion."
- Also, objects don’t need to be in motion to be moved — they start from rest.
- So: False — motion is not required; force is.
---
✘ False
- Heavier objects have more mass and thus more inertia. They require more force to accelerate (F = ma). So, false.
---
✔ True
- This is a key idea in Newton’s Second Law. Unbalanced forces cause acceleration, which includes all those changes.

1. When a force is balanced, there is no change in motion.
✔ True
- Balanced forces mean equal forces in opposite directions. This results in no net force, so the object will either stay at rest or continue moving at constant velocity (no acceleration).
---
2. Gravity is a force that pushes objects from the earth.
✘ False
- Gravity is an attractive force that pulls objects toward the Earth, not pushes them away.
---
3. Force is a push or a pull.
✔ True
- This is the basic definition of a force: any interaction that can cause an object to accelerate. It can be a push or a pull.
---
4. Force helps objects move faster.
✘ False (with nuance)
- A net force in the direction of motion can make an object speed up, but force can also slow down or change direction. So this statement is too general.
- Better answer: False — because force doesn’t *always* make things move faster (e.g., friction slows things down).
- So: ✘ False
---
5. Friction is always helpful.
✘ False
- Friction is not always helpful. For example, it causes wear on machine parts and reduces efficiency. But it’s useful for walking or stopping cars. So it depends.
---
6. Balanced forces do not cause a change in direction.
✔ True
- Balanced forces result in zero net force, so no acceleration. That means no change in speed or direction. The object maintains its current motion.
---
7. The amount of space between two objects or places is called position.
✘ False
- The amount of space between two points is distance.
- Position refers to where an object is located relative to a reference point.
---
8. A force that makes an object move is a push or a pull.
✔ True
- All forces are either pushes or pulls. If a force acts on an object, it could be due to a push or pull, causing motion.
---
9. A swing moving back and forth is an example of motion.
✔ True
- Motion is a change in position over time. A swing clearly changes position, so yes, it’s motion.
---
10. A force can change an object's motion.
✔ True
- Newton’s First Law: A force causes acceleration (change in motion), including speeding up, slowing down, or changing direction.
---
11. The force that pulls objects toward earth is called friction.
✘ False
- That force is gravity, not friction. Friction opposes motion between surfaces.
---
12. Speed is calculated using the distance traveled over the time it takes to travel.
✔ True
- Formula: Speed = Distance / Time — correct.
---
13. One way to measure distance is by temperature.
✘ False
- Temperature measures heat, not distance. Distance is measured with rulers, meters, etc.
---
14. An unbalanced force in a game of tug of war will cause one team to lose.
✔ True
- In tug of war, if one side pulls harder (unbalanced force), the rope moves toward that side, and the other team loses.
---
15. Motion is required to move an object.
✘ False
- This is confusingly worded. Motion is the result of movement. To move an object, you need a force, not "motion."
- Also, objects don’t need to be in motion to be moved — they start from rest.
- So: False — motion is not required; force is.
---
16. Heavier objects require less force to move.
✘ False
- Heavier objects have more mass and thus more inertia. They require more force to accelerate (F = ma). So, false.
---
17. An unbalanced force will cause an object to speed up, slow down or change direction.
✔ True
- This is a key idea in Newton’s Second Law. Unbalanced forces cause acceleration, which includes all those changes.
