6.8C- Which two measurements are needed to determine the speed of an object?

• Position and time

• Distance and time

• Position and direction

• Distance and direction

6.8D- During a science experiment, a student dropped a metal ball from a height of 150 m. The graph shows the distance the metal ball traveled from its initial position to where it hit the ground.

What information does the graph give you about the speed of the metal ball over time?

• The ball travels at a constant speed.

• The speed of the ball increases over time.

• The speed of the ball decreases over time.

• e speed of the ball increases at first, and then decreases as time increases.
