Back

A force that pulls objects toward each other, such as the force that pulls objects toward the Earth.

Front

What is friction?

Back

A force that opposes motion between two surfaces that are in contact.

Front

What is the formula for calculating speed?

Back

Speed = Distance ÷ Time.

Front

What is average speed?

Back

The total distance traveled divided by the total time taken.

Front

What is displacement?

Back

The shortest distance from the initial to the final position of an object, including direction.

Front

What is inertia?

Back

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

Front

What is a balanced force?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.
