PS: 5.1: Newton's 1st Law

Inertia is the tendency of an object to resist motion.

• True

• False

Newton’s first law of motion is also called the law of acceleration

• true

• false

If an object is at rest, inertia will keep it at rest

• true

• false

The inertia of an object is determined by its speed.

• true

• false

The speed of an object changes only when it is acted on by an unbalanced force.

• true

• false

A stationary object resists movement only because of gravity

• true

• false

The tendency of an object to resist a change in motion depends on its mass

• true

• false

If the net force acting on an object is zero, its inertia is also zero

• true

• false

When you are moving at a high rate of speed, inertia makes is hard to stop.

• true

• false

Newton’s first law of motion applies only to objects that are already moving

• true

• false
