Why is it important for basketball players to wear shoes with tread when playing?
to increase the speed of the player
to decrease the force between the player and the floor
to increase friction between the floor and the player’s feet

The box with a mass of 10 kg
Which of the following is an example of Newton’s first law of motion?

A person jumps to a dock from a boat, and the boat moves away from the dock.
A person standing on a bus moves backward when the bus suddenly moves forward.
Which of the following is NOT an example of friction?
using the brakes on your bike to slow you down
putting your hand out the window

Which object will have a STRONG force of gravity? Why?
monkey, has more mass
elephant, has more mass
mouse, has less mass
neither, there is no mass
A toy car pushed across the floor is observed to slow down and stop. Based on Newton's first law of motion, what is the BEST conclusion?
The car did not have enough mass to keep going.
There must have been an unbalanced force acting on the toy car.
The car must have been going slightly uphill.
The car ran out of gas.

Four different students take turns pushing a large, heavy ball on the school parking lot. What is the best way to determine which student used the most force to push the ball?
compare the ages of the students
compare the sizes of the students
compare the distances that the ball rolled
compare the number of times the ball was rolled
