On position time graph, with position on the y- axis and time on the x-axis, a change in direction is represented by:

• A line that is initially moving upwards,then turns downward

• A constantly rising line

• A flat, horizontal line

• A point at the intersection of the x and y axis

• A line that curves sharply

What is defined as an objects velocity at any given time

• Instantaneous velocity

• Immediate velocity

• Intimidation velocity

• Institutional velocity

When an object is in motion, it's ................... must change.

• Shape

• Size

• Acceleration

• Position

If someone is running -6m/s what is their speed?

• -6m/s

• 3m/s

• 6m/s

• -3m/s

Select the choice that does not describe an acceleration

• Pedaling faster

• turning a corner

• Coasting

• Hitting the breaks

Which statement describes best the motion diagram of an object in motion?

• a graph of the time data on a horizontal axis and the position on a vertical axis

• a series of images showing the positions of a moving object at equal time intervals

• a diagram in which the object in motion is replaced by a series of single points

• a diagram that tells us the location of the zero point of the object in motion and the direction in which the object is moving
