What is speed?

• The rate at which an object changes position
• The direction an object is moving
• moving fast
• change in speed or direction

Objects that are moving really fast have a lot of ________.

• Energy
• velocity
• knowlege
• gravity

When an object speeds up, slows down, stops, or starts is called?

• speed
• direction
• acceleration
• time

What are the two things that must be measured in order to find an objects velocity?

• speed and direction

• direction and time
• distance and rate

What happens to the energy of an object as its speed decreases?

• It stays the same
• It increases
• It decreases
• It first decreases then increases again

Speed -

• A measure that gives rate of change and position

• A measure that dissolves to one unit

• A measure of distance an object travels per unit of time.
