What is the word equation for speed?

• The word equation for speed is: Speed = Distance / Time.

• The word equation for speed is: Speed = Time / Distance.

• The word equation for speed is: Speed = Distance x Time.

• The word equation for speed is: Speed = Time x Distance.

How do we calculate average speed?

• By dividing the total distance by the total time

• By multiplying the total distance by the total time

• By adding the total distance and total time

• By subtracting the total time from the total distance

What do we mean when we talk about relative motion?

• The change in position of one object with respect to another object.

• The change in position of an object over time.

• The motion of an object in a straight line.

• The motion of an object in a circular path.

On a distance-time graph what is plotted on the X and Y axes?

• Distance is plotted on the Y-axis and time is plotted on the X-axis.

• Time is plotted on the Y-axis and distance is plotted on the X-axis.

• Both distance and time are plotted on the Y-axis.

• Both distance and time are plotted on the X-axis.

What does a horizontal line on a distance time graph mean?

• The object is stationary.

• The object is moving at a constant speed.

• The object is accelerating.

• The object is decelerating.
