Newton's _________ law of motions states that "An object at rest tends to stay at rest, and an object in motion tends to stay in motion with the same speed and in the same direction unless acted on by an unbalanced force."

• first

• second

• third

Object A is pushed with a 20N force. An object is pushed with a 10N force. Both objects move at the same distance. Is the mass of object B greater or less than the mass of object A?

• Less. More force is needed to accelerate an object of greater mass.

• More. Less force is needed to accelerate an object of greater mass.

• They are the same mass

If your speed is constant, can your velocity change?

• Yes. Your direction could change.

• Yes. Your speed can change.

• No. Your speed is constant.

How is the interia of an object related to an object's mass?

• The greater the mass, the greater the inertia.

• The greater the mass, the greater the friction.

• The greater the force, the greater the inertia.

What is interia?

• Force that keeps an object at rest or in motion unless acted on by an unbalanced force.

• Forces that only exist in space.

• The force of gravity acting on an object.
