Force, Motion, Energy Test

Front

What is the definition of force in physics?

Back

Force is a push or pull on an object that can cause it to change its velocity (speed or direction). It is measured in Newtons (N).

Front

What is motion?

Back

Motion is the change in position of an object over time relative to a reference point.

Front

What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, including kinetic, potential, thermal, and chemical energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state. It can be gravitational, elastic, or chemical.

Front

What type of potential energy is associated with an object's height?

Back

Gravitational potential energy is associated with an object's height above the ground.

Front

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing.

Front

What is chemical potential energy?

Back

Chemical potential energy is the energy stored in the bonds of chemical compounds, which can be released during a chemical reaction.

Front

How does mass affect the force required to move an object?

Back

The force required to move an object is directly proportional to its mass; more mass requires more force to achieve the same acceleration.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law of motion, force equals mass times acceleration (F = ma).
