Experimenting with Forces

Frank pushed two ball of different mass with the same force.

How will the motion of the ball with greater mass be different from the motion of the ball with less mass?

• • The ball with greater mass will move across a shorter distance.

• The ball with greater mass will move in a different direction.

• 
  The ball with greater mass will roll for a longer amount of time.

• 
  The ball with greater mass will move with more speed.

Zach, Beth, Randall, and Keisha are experimenting with forces. They each have a ball of the same mass and are going to move the balls on the same surface. The illustration shows their experimental setup.

The four students noticed that the balls rolled different distances. Which best explains why this happened?

• The balls experienced different amounts of friction.

• The balls did not all roll in the same direction.

• 
  The balls were pushed with different amounts of force.

• The balls were not all pushed at the same time.

Zeke and Tiffany are pushing on a car, but the car doesn't move. Why didn't the car move when they pushed on it?

• There is a greater opposing force acting on the parked car.

• 
  There is a smaller opposing force acting on the parked car.

• 
  The forces acting on the car are unbalanced.

• 
  The forces acting on the car are balanced.

Mr. Sanders asked his students to write an explanation for the relationship between force and motion. Which of the following descriptions correctly explains the relationship between force and motion?

• If something is moving, no force was applied to it.

• The greater the force, the greater the change in motion.

• 
  The more force applied to something, the less it moves.

• The smaller the force on an object, the greater the motion.

Kristen rolls two marbles with the same mass of 5 grams across the floor. One marble goes farther than the other. What most likely explains why one marble went farther?

• 
  The marble Kristen pushed are different colors.

• Kristen pushed one marble with greater force.

• Kristen measured the distances very carefully.

• 
  The floor is very flat and very smooth.
