Practice Test - Forces and Newton's Laws of Motion

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force.

Front

What is Newton's 2nd Law of Motion?

Back

Force = Mass × Acceleration (F = ma). This law explains how the velocity of an object changes when it is subjected to an external force.

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is an unbalanced force?

Back

A force that causes an object to change its state of motion (acceleration).

Front

What is a balanced force?

Back

Forces that are equal in size but opposite in direction, resulting in no change in motion.

Front

What is mass?

Back

The amount of matter in an object, typically measured in kilograms (kg).

Front

What is acceleration?

Back

The rate of change of velocity of an object, measured in meters per second squared (m/s²).

Front

How do you calculate mass using force and acceleration?

Back

Mass = Force / Acceleration.

Front

What is the formula for calculating force?

Back

Force = Mass × Acceleration (F = ma).

Front

What is the role of frictional force?

Back

Frictional force opposes the motion of an object, acting in the opposite direction to the applied force.
