1. The greater the ________ the easier the object will move.
-
Answer:
force
-
Explanation: The greater the force applied to an object, the easier it is to move the object. Force is directly related to motion according to Newton's Second Law of Motion: \( F = ma \) (Force = mass × acceleration).
---
2. To do the job in less time and with less energy, use a ________.
-
Answer:
machine
-
Explanation: Machines help reduce the effort required to perform tasks by either increasing the force applied or changing the direction of the force. This allows work to be done more efficiently.
---
3. That rock will roll down the hill due to the force of ________.
-
Answer:
gravity
-
Explanation: Gravity is the force that pulls objects toward the center of the Earth. When a rock is on a hill, gravity causes it to roll downhill.
---
4. To make something ________ both ends need to have the same weight.
-
Answer:
balance
-
Explanation: Balance refers to the state where an object is stable and not tipping over. For an object to be balanced, the forces acting on it must be equal on both sides.
---
5. It takes ________ to get a job done.
-
Answer:
energy
-
Explanation: Energy is the capacity to do work. Without energy, no task can be performed. Work is defined as the transfer of energy.
---
6. ________ is the idea that something in motion will remain in motion, and something at rest will remain at rest, unless affected by an outside source.
-
Answer:
inertia
-
Explanation: Inertia is the tendency of an object to resist changes in its state of motion. This principle is described by Newton's First Law of Motion, also known as the Law of Inertia.
---
7. It would be more difficult to ________ a wagon if it didn’t have wheels.
-
Answer:
push
-
Explanation: Wheels reduce friction, making it easier to move objects like wagons. Without wheels, pushing the wagon would require much more effort due to increased friction between the ground and the wagon.
---
8. If you have a few people ________ on the rope, the box will be easier to move.
-
Answer:
pull
-
Explanation: Pulling is the action of exerting a force to draw an object toward oneself. Having multiple people pulling on a rope increases the total force applied, making it easier to move the box.
---
9. ________’s theories on motion are still believed correct today.
-
Answer:
Newton
-
Explanation: Sir Isaac Newton formulated the three laws of motion, which are fundamental principles in physics and are still widely accepted today.
---
10. We added wheels to our bureau to create less ________ when we move it.
-
Answer:
friction
-
Explanation: Friction is the force that resists the relative motion of surfaces sliding against each other. Adding wheels reduces friction, making it easier to move the bureau.
