A force that opposes motion between two touching surfaces is called:

• friction

• acceleration

The rate an object is moving relative to a reference point is its

• velocity.

• speed.

• deceleration rate.

• mechanical potential energy rate.

The speed at which an object is moving in a specific direction is its

• speed.

• acceleration rate.

• velocity.

• mechanical potential energy rate.

An object's average speed is found by dividing the total distance the object travels by the total

• mass of the object.

• acceleration of the object.

• specific gravity of the object.

• time it takes to move that distance.

Newton's First Law of Motion states that an object in motion tends to stay in motion unless it

• starts to decelerate.

• runs out of kinetic energy.

• is acted upon by another force.

• approaches the speed of light.

Newton's Second Law of Motion says that the acceleration of an object depends on the object's mass and the

• equation E=MC^2E=MC​2

  
  

  ​​.

• amount of force applied to the object.

• negative acceleration factor.

• amount of atoms the object has.

Newtons Third Law of Motion states that for every action there is an equal and opposite reaction. Which of these illustrates Newton's Third Law?

• Two students of similar mass run into each other. They bounce off each other when they collide.

• Two students of similar mass run side by side into a wall and punch holes of equal size before emerging on the other side.

• Two students of similar mass run in opposite directions, but one accelerates at twice the rate of the other.

• Two students of similar mass run at the same speed in opposite directions on a track. They will collide with 400 Newtons of force in 400 meters.
