Physics Quiz

What is the force exerted by an object equal to?

• The force that the object exerts on itself

• The force that the second object exerts on the first

• The weight of the object

• The speed of the object

What determines the motion of an object?

• The color of the object

• The shape of the object

• The sum of the forces acting on it (Net force)

• The size of the object

If the total force on an object is not zero, what will happen to its motion?

• It will remain constant

• It will change

• It will reverse

• It will stop

If the net force on an object is zero, what will happen to its motion?

• It will remain constant

• It will change

• It will reverse

• It will stop

What effect does increasing the mass of an object have on the force needed to change its motion?

• Decreases the force needed

• No effect on the force needed

• Increases the force needed

• The force needed becomes zero

What is Newton's first law of motion also known as?

• The law of gravity

• The law of acceleration

• Inertia

• The law of action-reaction

According to Newton's first law of motion, what will an object at rest do unless acted upon by an unbalanced force?

• It will move at a constant velocity.

• It will accelerate.

• It will stay at rest.

• It will decrease its mass.

What will objects that are in motion do unless acted upon by an unbalanced force?

• They will stop immediately.

• They will change direction.

• They will stay in motion at the same speed and in the same direction.

• They will increase their mass.

What does it mean when it is said that objects resist changes in motion?

• Objects will always move in a circular path.

• Objects will spontaneously change their state of motion.

• The heavier the object, the more of a delay in changing motion.

• Objects prefer to be in a state of rest.

What does Newton's second law of motion state about acceleration?

• The acceleration of an object is inversely proportional to the mass of the object and directly proportional to the force applied.

• The acceleration of an object is directly proportional to the mass of the object and inversely proportional to the force applied.

• The acceleration of an object depends only on the mass of the object, regardless of the force applied.

• The acceleration of an object depends on the mass of the object and the amount of force applied.
