Force and Motion

Front

What is force?

Back

A push or pull on an object that can cause it to accelerate.

Front

What is motion?

Back

The change in position of an object over time.

Front

What is friction?

Back

A force that opposes the motion of an object, acting in the opposite direction.

Front

What is Newton's First Law of Motion?

Back

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

Front

What is Newton's Second 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 Third Law of Motion?

Back

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

Front

What is inertia?

Back

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

Front

What is mass?

Back

The amount of matter in an object, usually measured in grams or kilograms.

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 gravitational force?

Back

The attractive force between two objects due to their mass.
