What is a push or a pull on an object called?
- Force
- Energy
- Mass
- Weight
Show answer
Answer: A. Force
A force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can be described as a push or a pull on an object.
What happens to the motion of an object when equal forces are applied in opposite directions?
- Moves forward
- Moves backward
- Remains stationary
- Starts spinning
Show answer
Answer: C. Remains stationary
When equal forces are applied in opposite directions, they balance each other out, resulting in no net force. Therefore, the object remains stationary.
What changes in an object when a force is applied to it but it doesn’t necessarily move?
- Its color
- Its state of matter
- Its speed
- Its shape
Show answer
Answer: D. Its shape
When a force is applied to an object, without causing movement, it can change the shape of the object by compressing it or bending it.
Which of these motions is caused by a repetitive force?
- Rolling down a hill
- Swinging on a swing
- Running on a track
- Sliding on ice
Show answer
Answer: B. Swinging on a swing
Swinging on a swing is an example of periodic motion, caused by a repetitive force that moves the swing back and forth.
What describes the energy possessed by a moving object?
- Potential energy
- Kinetic energy
- Thermal energy
- Chemical energy
Show answer
Answer: B. Kinetic energy
Kinetic energy is the energy possessed by an object due to its motion. Any moving object has kinetic energy.
