Quiz on Newton's Laws of Motion

What does the law of inertia state?

• An object at rest will remain at rest.

• An object will accelerate if a net force acts on it.

• For every action, there is an equal and opposite reaction.

• An object will move faster if it has more mass.

What is the primary factor that determines the inertia of an object?

• The net force acting on it

• The object's mass

• The distance it travels

• The object's velocity

In the context of the law of acceleration, what happens if the net force is constant?

• Acceleration is directly proportional to mass.

• Acceleration is inversely proportional to mass.

• Acceleration remains constant regardless of mass.

• Acceleration is independent of net force.

What is the equation that represents the law of acceleration?

• ΣF = m + a

• ΣF = ma

• F = m/a

• F = ma

What does the law of interaction focus on?

• Forces acting on a single object

• Forces exerted by two bodies on each other

• The acceleration of an object

• The mass of an object

According to the law of interaction, what is true about action-reaction pairs?

• They do not affect each other.

• They act on the same object.

• They are equal and opposite.

• They can vary in strength.

What is the net force acting on an object in equilibrium?

• Greater than zero

• Less than zero

• Equal to zero

• Variable depending on mass

If a squirrel is gliding at constant velocity, what can be said about the forces acting on it?

• The net force is less than its weight.

• The net force is equal to the air resistance.

• The net force is zero.

• The net force is greater than its weight.

What is the relationship between mass and acceleration when the net force is constant?

• Mass and acceleration are equal.

• Mass has no effect on acceleration.

• Mass is inversely proportional to acceleration.

• Mass is directly proportional to acceleration.

What is the normal force acting on a 3.00 kg book at rest on a table?

• 3.00 N

• 29.4 N

• 9.8 N

• 0 N
