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?
