• speed

• time

• distance

What information do you need in order to find the speed of a moving object?

• the mass of the object and the distance it moved

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

• the position of the object and the force used to move it to that position

• the length of the object and the direction in which it moved

Your friend kicks a rolling ball with a certain force. Then you kick the same ball with a larger force. What will most likely happen?

• The ball will move faster and farther when your friend kicks it.

• The ball will move faster and farther when you kick it.

• The ball will move more slowly and farther when you kick it.

• The ball will move faster and not as far when your friend kicks it.
