Chapter 2 Test- Force and Motion

when an object changes its position relative to a reference point.(moves)

• Motion

• Speed

• Acceleration

• Position

the speed at one point in time.

• Velocity

• Instantaneous speed

• Average speed

• Constant speed

A place or object used for comparison to determine if something is in motion

• Velocity

• Acceration

• Position

• Reference Point

how far something has moved

• Distance

• Displacement

• Position

• Velocity

is the distance and direction of an object's change in position from the starting point.

• Distance

• Displacement

• Velocity

• Acceration

the distance an object travels per unit of time.

• speed

• distance

• displacement

• position

No change in speed; no calculation needed

• speed

• instantaneous speed

• average speed

• constant speed

location relative to a reference point

• distance

• position

• velocity

• speed

describes speed of motion when speed is changing; the total distance traveled divided by the total time of travel.

• speed

• instantaneous speed

• average speed

• constant speed

the change in velocity (m/s²)

• Speed

• Direction

• Position

• Acceleration
