Motion in 1D

Is Displacement a Scalar or Vector?

• Scalar

• Vector

Which of the following is an example of a common Vector?

• Displacement

• Time

• Motion

• Acceleration

Use the velocity vs time graph to determine the correct position vs time graph

• 
• 
• 
• 

Based on the graph above, what is the direction the object is moving from 6-10 seconds

• positive direction

• negative direction

• at rest

• no direction

Based on the graph above, the object is ______ from 0-4 seconds

• moving in the positve direction and speeding up

• moving in the negative direction at a constant velocity

• moving in the positive direction at a constant velocity

• at rest

• moving in the negative direction and speeding up

As an object is thrown up, If up is considered positive and down is considered negative, what is the direction of the velocity and acceleration of the object at its highest point

• Velocity: 0 Acceleration: 0

• Velocity: 0 Acceleration: -

• Velocity: 0 Acceleration: +

• Velocity: - Acceleration: 0

A position-time graph is given to you. Write the letter for the object that has the greatest constant velocity.

An old car has a rusty engine, leaking oil drops which hit the street at regular intervals. The oil drop pattern depicts

• a constant velocity

• an accelerated motion

• an increasing accelerated motion

• Impossible to tell without any distance-time data.

On this position vs time graph, what is the velocity from 15 to 40 seconds?

• -4 m/s

• -10 m/s

• -25 m/s

• -100 m/s

Which graph shows the greatest acceleration?

• A

• B

• C

• D
