Force and Motion

Front

What is the definition of force?

Back

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

Front

What is motion?

Back

The change in position of an object over time.

Front

What is the relationship between force and motion?

Back

Force causes motion; without force, an object at rest will stay at rest.

Front

What is speed?

Back

A measure of how fast something moves, calculated as distance divided by time.

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 does it mean to accelerate?

Back

To increase the speed of an object or change its direction.

Front

What is the effect of increasing force on an object's motion?

Back

Increasing force results in greater acceleration and distance traveled.

Front

What is friction?

Back

A force that opposes motion between two surfaces in contact.

Front

How does mass affect the motion of an object?

Back

More mass means more force is needed to achieve the same acceleration.

Front

What is inertia?

Back

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