Science Final Review 2nd Semester MCMS

If you know the distance an object has traveled in a certain amount of time, you can determine

• the size of the object.

• the speed of the object.

• the location of the object.

• the velocity of the object.

When you know both the speed and the direction of an object’s motion, you know the

• average speed of the object.

• acceleration of the object.

• distance the object has traveled.

• velocity of the object.

Changing direction is an example of a kind of

• acceleration.

• speed.

• velocity.

• constant rate.

What part of a car causes negative acceleration?

• Steering wheel

• Gas pedal

• Brake pedal

• Blinker
