• Non-contact force

• Equilibrium

• System

• Inertia

Two blocks sit side-by-side at rest on a frictionless surface. A force of 15 N is applied to the left-hand block, which has a mass of 3.0 kg. If the blocks accelerate to the right at a rate of 3.0 m/s2, what is the mass of the right-hand block?

• 2.0 Kg

• 2.5 Kg

• 3.0 Kg

• 15.0 Kg

A baseball player hits a baseball with a bat. Which of the following statements about the forces involved is correct?

• The force of the ball on the bat is less than the force of the bat on the ball.

• The ball exerts no force on the bat, since the ball is pushed backwards.

• The relative size of the force of the ball on the bat and the bat on the ball depends on the speed of the swing.

• The force of the ball on the bat is equal in size to the force of the bat on the ball.

In Physics, what is equilibrium?

• A force exerted when an object is in contact with another object

• A force that can be exerted over a distance and does not require contact in order to be exerted

• An object's tendency to resist changes in its motion

• A situation where the net force on an object is zero

If the force acting on an object is tripled, what will happen to its acceleration, if the mass of the object is kept constant?

• The acceleration will decrease by a factor of 3.

• The acceleration will triple.

• There will be no acceleration.

• The acceleration will not change.
