Force and Motion

Front

What is force?

Back

A push or pull on an object that can cause it to move, stop, or change direction.

Front

What is motion?

Back

The change in position of an object over time.

Front

What is speed?

Back

The distance traveled per unit of time, often measured in meters per second (m/s) or feet per second (ft/s).

Front

How do you calculate average speed?

Back

Average speed = Total distance traveled / Total time taken.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (only magnitude), while velocity is a vector quantity (magnitude and 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 a net external force.

Front

What is friction?

Back

A force that opposes the motion of an object, caused by the contact between surfaces.

Front

What is a ramp?

Back

An inclined surface that allows objects to be raised or lowered with less force than lifting them vertically.

Front

What is the relationship between force and motion?

Back

Force causes changes in motion; without force, an object's motion will not change.

Front

What is inertia?

Back

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