Newton's Laws of Motion

It is

...

True or False; Newton's first law of motion applies only to objects that are already moving.

False

Describe how inertia affects motion.

If an object is already at rest, inertia will keep it at rest. If the object is already moving, inertia will keep it moving.

What is inertia

Inertia is the tendency of an object to resist a change it its motion.

What is the relationship between mass and inertia?

The inertia of an object depends on its mass, objects with greater mass also have greater inertia.

True of False; If an object is at rest, inertia will keep it at rest.

True

True or False; Inertia is the tendency of an object to resist motion.

True

True or False; The speed of an object changes only when it is acted on buy an unbalanced force.

True

True or False; The tendency of an object to resist a change in motion depends on its mass.

True

True or False; When you are moving at a high rate of speed, inertia makes it hard to stop.

True

Newton's first law of motion states that an object's motion will not change unless.. a. the net force acting on it is greater than zero. b. a force continues to be applied to the object. c. its inertia is stronger than the applied force. d. the object has no inertia.

b. a force continues to be applied to the object.
