Force and Motion Exam

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 at a constant velocity unless acted upon by a net external force.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is gravity?

Back

A force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What is mass?

Back

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

Front

What is force?

Back

A push or pull on an object that can cause it to accelerate, measured in newtons (N).

Front

What is acceleration?

Back

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

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the relationship between mass and acceleration?

Back

As mass increases, for a given force, acceleration decreases.

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).
