Kinematics Review 2

A car has a negative velocity and a positive acceleration. The car is___________

• Speeding up

• Slowing down

• Traveling at a constant velocity

• At rest

A car is traveling with a positive velocity and and positive velocity. The car is _______________

• speeding up

• slowing down

• moving at constant velocity

• at rest

A car is traveling with a negative velocity and 0 acceleration. The car is______________

• speeding up

• slowing down

• traveling at a constant velocity

• at rest

Which of the following list of measurements has only vectors listed?

• Displacement, Velocity, Time, Acceleration

• Distance, Velocity, Acceleration, Force

• Displacement, Velocity, Acceleration, Force

• Distance, Speed, Acceleration, Time

According to the graph, when is the object speeding up

• From 4-5 seconds and from 13 to 18 seconds

• from 6 to 18 seconds

• from 4 to 9 seconds

• from 6 to 9 seconds

According to the graph, when was the object slowing down

• from 13 to 18 seconds and from 4 to 6 seconds

• from 13 to 18 seconds

• from 0 to 6 seconds

• from 0 to 6 seconds and from 13 to 18 seconds

According to the graph, when is the object moving at a constant velocity?

• From 4 to 9 seconds

• From 9 to 13 seconds

• From 0 to 4 seconds and from 9 to 13 seconds

• At 6 and 18 seconds

On Earth, when an object is thrown up, what is the object's velocity at it's highest point (right before it comes back down)?

• 0 m/s

• 9.8 m/s²

• -9.8 m/s²

• Depends on the object

Distance is always equal to displacement.

• True

• False

Answer explanation

Distance is the TOTAL amount traveled regardless of direction. Displacement is how far from where you started. If you travel 3 meters east and then 3 meters west your distance is 6 m but your displacement is zero.

What unit is not used for acceleration?

• m/s^2

• ft/s^2

• m/s

• miles/hr^2
