Physics Study guide (velocity and displacement w/ constant acceleration)

For the following, match the unit to its concept.

Meter C A.velocity Meter/ second A B.time Meter/second^2 D C.displacement Second B D.Acceleration

When a car's velocity is positive and its acceleration is negative, what is happening to the car's motion?

The car slows down.

When a ca's velocity is negative and its acceleration is negative, what is happening to the car's motion ?

The car speeds up

If you know a car's acceleration, the information you must have to determine if the car's velocity is increasing is the

direction of the car's initial velocity

What is the SI unit of acceleration?

m/s^2

Which of the following units is the SI unit of velocity?

meter per second

Acceleration is defined as

the rate of change of velocity

What is the Speed of an object at rest?

0.0 m/s

For the following, write down two (2) examples of magnitude. Make sure you use units.

9 m/s 11 m/s

Which of the following is the equation for acceleration?

A= v/t

The acceleration varies

What does the graph below illustrate about acceleration?
