What is necessary to determine the speed of an object?

• the mass and volume of the object

• the shape of the object and the distance it moved

• the mass of the object and the time it took to move

• the distance moved by the object and the time it took to move

How can the speed of an object best be determined?

• distance traveled divided by time it took to travel

• time it took to travel divided by distance traveled

• distance traveled divided by speed traveled

• speed traveled divided by distance traveled

Which tools will be most helpful to a scientist measuring motion?

Which information is needed to determine the speed of an object?

• the weight of the object and the distance it travels

• the pull of gravity on the object and the amount of time it travels

• the inertia of the object and the amount of force that is pushing it

• the distance the object travels and the time it takes to travel that

  distance

The graph shows the speed a car traveled in a certain amount of

time. Which best describes the motion of the car?

• The car was not moving until the rate of speed increased.

• The car was moving at a constant rate and then decreased speed.

• The car was not moving until the rate of speed decreased.

• The car was moving at a constant rate and then increased speed.
