Back

7.45 m.

Front

Define mass.

Back

Mass is the amount of matter in an object, typically measured in kilograms.

Front

Define weight.

Back

Weight is the force exerted by gravity on an object, calculated as mass times the acceleration due to gravity.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the formula for calculating velocity?

Back

Velocity = Displacement / Time.

Front
