Question 1 options:


Speed


Acceleration


Displacement


Velocity

Which of the following depends on an object's displacement not distance from the starting point?
Question 2 options:


Acceleration

Velocity

What is the average speed of an object that travels 50 miles in 2 hours?
Question 3 options:


25 mph


50 mph


100 mph


2 mph

Which of the following is an example of velocity?
Question 4 options:


100 mph


25 east


50 mph east


100 miles east

Which of the following is defined as displacement over change in time?
Question 5 options:


Velocity


Acceleration


Speed


Displacement

What is the velocity of an car that travels 50 miles north, turns around and travels 50 miles south, in 5 hours?
Question 6 options:


25 mph north


2 mph south


0


5 mph south

I dont need number 7

Macon is 50 miles from Atlanta. If the time of the trip increases, what happens to the speed?
Question 8 options:


It decreases


It increases


It stays the same because the distance stays the same


It averages out to the same speed.

Answer 1

1. Speed, since we know that
`s=(d)/(t)`, where s is speed, d is distance and t is time

2. Velocity, for velocity you need to consider the direction and displacement gives the direction of travel.

3. 25 mph, because
`s=(d)/(t) =(50)/(2) =25mph`

4. 50 mph east, velocity unlike speed has direction.

5.Velocity, displacement gives the formula
`v=(d)/(t)` direction.

6. 0, the displacement is zero so velocity is zero

7. It decreases, speed is inversely proportional to time
