Motion and forces study tool (8th grade)

when an object changes its position.

• Speed

• Motion

• Displacement

• Average speed

an indicator that orients you; the place from where you measure, record, or witness an event.

• Velocity

• Distance

• Reference point

• Acceleration

how far an object has moved.

• Reference point

• Distance

difference from starting to ending point.

• Distance

• Displacement

Speed

• the speed of an object and the direction of its motion.

• the distance an object travels per unit of time.

• rate of change of velocity over time.

• when an object speeds up

Average speed

• the speed at any given point.

• total distance traveled divided by total time traveled.

Instantaneous speed

• the speed at any given point.

• total distance traveled divided by total time traveled.

Velocity

• the speed of an object and the direction of its motion.

• the distance an object travels per unit of time.

Acceleration

• total distance traveled divided by total time traveled.

• when an object slows down.

• rate of change of velocity over time.

• the speed at any given point.

The equation to find speed and velocity are different

• True

• False
