Newton's Laws in systems reading quiz

What does Newton's First Law, also known as the law of inertia, state?

• An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.

• The acceleration of an object depends on the net force acting upon it and the object's mass.

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

• The force of gravity acts on all objects equally.

According to Newton's Second Law, what happens when you push a shopping cart harder?

• The cart accelerates faster.

• The cart becomes heavier.

• The cart moves in a circular path.

• The cart stops immediately.

What is the formula expressed by Newton's Second Law?

• F = ma

• E = mc^2

• P = mv

• V = IR

What does Newton's Third Law state about forces?

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

• An object at rest stays at rest unless acted upon by an external force.

• The acceleration of an object depends on the net force acting upon it.

• The force of gravity is constant.

Why is a heavy truck harder to start moving than a small car, according to the passage?

• Because it has greater inertia due to its mass.

• Because it has more wheels.

• Because it requires more fuel.

• Because it is designed to move slowly.
