Motion Test

Two students on opposite sides of a box apply forces to the box. What must be true if the box doesn't accelerate?

• The forces are equal in strength and in opposite directions.

• One student must be pushing the box while another student pulls it.

• One student is applying a greater force.

• Both students are applying forces in the same direction.

How do you calculate distance?

• Distance divided by time.

• Displacement divided by time.

• Speed multiplied by time.

• Displacement divided by velocity.

What is motion?

• the stopping of an object to a frame of reference

• a change in position relative to a frame of reference

• the middle ground between light and shadow, between science and superstition, and it lies between the pit of man's fears and the summit of his knowledge

• a change in the time in which it takes to get an office referral
