Unit 12: Forces and Motion Review

The speed formula to solve the average speed of a moving object is:

• Speed = Distance x Time

• Speed = Meters x Seconds

• Speed = Distance divided by Time

• Speed = Velocity + Acceleration

To solve for the distance, a student would use this formula

• D = Speed divided by Time

• D= Speed x Time

• D = Acceleration x Velocity

• D = Meters divided by Acceleration

To solve a story problem about time, a person would use this formula:

• Time = Seconds/Per Second

• Time = Distance x Acceleration

• Time = Time multiplied by Speed

• Time = Distance divided by Speed

What is the definition of speed?

• Speed is dangerous.

• Speed is the measure of distance and time.

• Speed is the measure of distance and volume.

• Speed is the comparing of distance of a car and a runner.

The measure of distance and time along with directions is called:

• Distance

• Acceleration

• Velocity

• Friction

Motion can change acceleration in several ways. Which ones are correct according to our science discussions?

• increase, decrease, change direction

• stop, go, motionless

• hop, jump, tip toe

• fly, swim, walk

100 miles east is an example of:

• speed

• direction

• velocity

• friction

25 mph is an example of:

• velocity

• friction

• speed

• acceleration

• Newton's Law

• acceleration to occur

• friction

• velocity
