Front

What is the tendency of an object that is at rest to stay at rest or if in motion to stay in motion?

Back

Inertia

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = ma)

What is the unit of force in the International System of Units (SI)?

Back

Front

What is the difference between mass and weight?

Back

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