• Acceleration

• Velocity

• Displacement

Multiple Choice

The object in previous slide moves with constant speed. How do you know?

• The graph is a straight line, indicating the velocity does not change.

• The graph shows increasing position, which means the object is slowing down.

• The graph is curved, which shows a change in velocity.

Multiple Choice

Object 1 is _______

• Moving with positive  velocity

• Moving with negative  velocity

• At rest ( not moving)

Multiple Choice

Object 2 is _______

• Moving with positive  velocity

• Moving with negative  velocity

• At rest ( not moving)

Multiple Choice

Object 3 is _______

• Moving with positive  velocity

• Moving with negative  velocity

• At rest ( not moving)

​

​1. Position vs. Time Graphs: Slope represents velocity

Multiple Choice

How would you describe the motion of the object in this graph?

• The object’s velocity is increasing.

• The object’s position is changing at a constant rate.

• The object is not moving.

Multiple Choice

In this graph the velocity is __________

• Constant - positive

• Increasing - negative

• Constant - negative

Multiple Choice

In this graph the velocity is __________

• Constant - positive

• Increasing - positive

• Increasing - negative

Multiple Choice

In this graph the velocity is __________

• Constant

• Changing

• Zero

Multiple Choice

Both graphs show _________
