Chapter 6 Newtons Second Law

According to Newton's Second Law of Motion, what happens when a net force acts on an object?

• The object remains at rest.

• The object accelerates.

• The object moves at a constant velocity.

• The object decreases in mass.

What is the definition of acceleration as described in the material?

• Change in position per unit of time

• Change in velocity per unit of time

• Change in mass per unit of time

• Change in force per unit of time

Which of the following best describes the condition for mechanical equilibrium?

• The net force is greater than zero.

• The net force is less than zero.

• The net force is zero.

• The net force is equal to the object's mass.

If a football is kicked and accelerates, what can be said about the net force acting on it?

• The net force is zero.

• The net force is less than zero.

• The net force is greater than zero.

• The net force is equal to gravity only.

When observing the motion of a single coffee filter as it falls, what should you look for according to the material?

• Whether it changes color

• Whether it accelerates or moves with constant velocity

• Whether it spins in the air

• Whether it bounces on the ground

If you double the net force acting on an object, what happens to its acceleration?

• The acceleration is halved

• The acceleration remains the same

• The acceleration doubles

• The acceleration triples

If a loaded shopping cart and an empty shopping cart are pushed with the same force, which will accelerate more?

• The loaded cart

• The empty cart

• Both will accelerate equally

• Neither will accelerate

According to Newton's second law, what is the relationship between the net force on an object and its acceleration?

• The net force is inversely proportional to the acceleration.

• The net force is directly proportional to the acceleration.

• The net force is unrelated to the acceleration.

• The net force is equal to the mass of the object.

What is the formula for acceleration according to Newton's second law?

• acceleration = mass / net force

• acceleration = net force / mass

• acceleration = net force × mass

• acceleration = mass × velocity

What are fluids in the context of friction?

• Liquids and gases because they flow.

• Only liquids because they are wet.

• Only gases because they are light.

• Solids that can change shape.
