Newton's Laws

A bowling ball is rolled with a certain speed and strikes a bowling pin with a force indicated by the arrow in this illustration. When the bowling ball strikes the bowling pin, the force applied by the pin to the ball -

• depends on the mass of the bowling pin.

• is equal to the force applied by the ball.

• must be zero, since the pin is not moving.

• is equal to the force of gravity on both.

Which of the following is a statement of Newton's First Law of Motion?

• An object will remain at rest or in uniform motion unless acted upon by a net external force.

• The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

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

• The force of gravity acts between all masses.

What does Newton's Second Law of Motion state about the relationship between force, mass, and acceleration?

Which of the following scenarios best illustrates Newton's Third Law of Motion?

• A book resting on a table.

• A rocket launching into space as it expels gas downwards.

• A car accelerating on a straight road.

• A pendulum swinging back and forth.

If a car is moving at a constant velocity, what can be said about the net external force acting on it according to Newton's First Law?

• The net external force is zero.

• The net external force is equal to the weight of the car.
