Newton's First Law Quiz--AP1

What is the definition of inertia?

• The speed at which an object moves

• The force that causes an object to move

• Resistance of an object to changes in its motion or rest

• The ability of an object to move easily

Give an example of inertia in everyday life.

• Car stopping abruptly

• A plane taking off from a runway

• A person jumping off a diving board

• A ball rolling down a hill

How does mass affect inertia?

• Mass affects inertia by increasing it.

• Mass only affects inertia in certain situations.

• Mass decreases inertia.

• Mass has no effect on inertia.

State Newton's first law of motion.

• An object at rest will stay at rest, and an object in motion will stay in motion with a different speed and in a different direction, unless acted upon by an external force.

• An object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction, unless acted upon by an external force.

• An object at rest will start moving in the opposite direction, and an object in motion will change its speed and direction, unless acted upon by an external force.

• An object at rest will stay at rest, and an object in motion will stop immediately, unless acted upon by an external force.

Explain the concept of inertia with an example.

• Inertia is the tendency of an object to resist changes in its motion.

• Inertia is the tendency of an object to change its shape.

• Inertia is the tendency of an object to accelerate in its motion.

• Inertia is the tendency of an object to attract other objects.

What happens to an object at rest when no external force is applied to it?

• It accelerates

• It remains at rest

• It starts moving

• It changes direction

How does inertia relate to the motion of objects?

• Inertia is the tendency of an object to resist changes in its motion.

• Inertia is the tendency of an object to move in a straight line at a constant speed.

• Inertia is the tendency of an object to accelerate when a force is applied to it.

• Inertia is the tendency of an object to change its shape when a force is applied to it.

Provide an application of Newton's first law in sports.

• Basketball bouncing on the court

• Baseball being hit by a bat

• Tennis ball being served over the net

• Soccer ball rolling on the field

Why is it easier to push a lighter object than a heavier one?

• Less force required

• Less friction

• Less resistance

• Less mass and inertia

How does inertia affect the movement of a car during sudden braking?

• Inertia causes the car to move backwards during sudden braking.

• Inertia causes the car to stop immediately during sudden braking.

• Inertia has no effect on the movement of a car during sudden braking.

• Inertia causes the car to continue moving forward even after sudden braking.
