What does speed measure?

• How fast an object is going

• How far an object has traveled

• The rate at which an object slows down

• The rate at which an object speeds up

What does acceleration measure?

• How fast an object is going

• The fastest speed that an object can reach

• The force with which an object travels

• The rate at which speed or direction changes

When acceleration goes up, what happens to the speed?

• The speed stays the same.

• The speed decreases.

• The speed increases.

• The speed increases the decreases.

Fill in the blank: Acceleration is change in _____ divided by change in time.

True or false: Constant speed means that the speed is changing as an object goes.

• True

• False
