Forces and Motion

Front

What is Newton's Third Law of Motion?

Back

For every action force, there is an equivalent reaction force in the opposite direction.

Front

What does Newton's Second Law state?

Back

F=ma (Force equals mass times acceleration).

Front

What is acceleration?

Back

A change in speed, a change in direction, or both.

Front

What is a reference point?

Back

A stationary object used to determine the motion of another object.

Front

What is inertia?

Back

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

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F=ma).

Front

What is velocity?

Back

The speed of an object in a specific direction.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is gravitational force?

Back

The attractive force between two objects due to their mass.

Front

What is friction?

Back

A force that opposes the motion of an object.
