Introduction to Motion

In order to accurately describe motion you must use this type of point.

• Resistance

• Reference

• Sharp

• Elastic

Motion is defined as a change in an object's ____________________.

• Size

• Velocity

• Speed

• Position

What is distance?

• The length that sound travels.

• The length of your right arm.

• The length that an object travels.

• The height of the nearest building.

Displacement is defined as:

• How far from the starting point that an objects ends up.

• The length that an object travels.

• How fast an object moves.

• How often an object moves.

Displacement must reference both of these.

• Speed and mass.

• Direction and velocity.

• Direction and speed.

• Distance and direction.

Displacements can be added if they occur in:

• Opposite directions

• Different directions

• The same direction

• Any direction

Speed and velocity are synonyms:

• True

• False

Speed is defined as:

• Time divided by distance

• Velocity divided by time

• Time multiplied by distance

• Distance divided by time

The three types of speed that we studies are:

• Constant, Average, and Instantaneous

• Variable, Average, and Instantaneous

• Constant, Slow, and Instantaneous

• Constant, Average, and Gradual

On a graph of distance versus time a horizontal line means:

• Acceleration

• Deceleration

• Irregular motion

• No motion
