Front

What coefficient of friction would you use to calculate friction of steel sliding on steel?

Back

0.57

Front

Friction is an example of _____________.

Back

a contact force

Front

If the mass of an object is 1000 kg on Earth, what is its mass on the moon?

Back

1000kg

Front

An object can be moving for 10 seconds and still have zero displacement. True or False?

Back

True

Front

Define gravitational force.

Back

The force of attraction between two masses.

Front

What is the formula for calculating weight?

Back

Weight = mass × gravitational acceleration (W = mg).

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.

Front

What is the coefficient of friction?

Back

A numerical value that represents the frictional force between two surfaces.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.
