Front

What is an example of velocity?

Back

A car driving 55 miles per hour south.

Front

What is mass?

Back

A measure of the amount of matter an object contains.

Front

What is the formula for calculating force?

Back

Force = Mass × Acceleration (F = m × a)

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What does Newton's First Law of Motion state?

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 inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the unit for force?

Back

Newton (N)
