Which will most likely happen when additional forces act on a moving

object?

• The mass of the object will change.

• The object will either speed up or slow down.

• The object will begin moving at a constant speed.

• The friction forces on the object will remain the same.

Mr. Smith’s class is experimenting with two toy cars that have the same

mass. If one car is pushed harder than the other car is pushed, what will

most likely happen?

• The car that was pushed harder will be less affected by gravity.

• The car that was pushed harder will be more affected by gravity.

• The car that was pushed harder will travel farther than the other car.

• The car that was pushed harder will not travel as far as the other car.

Which must happen for a moving car to change direction?

• The car must slow down.

• Gravity must act on the car.

• The mass of the car must change.

• Another force must act on the car.

Two teams are playing “tug-of-war” with a long rope. Both teams have

six members each that are all about the same size and strength. During

the game, two members of the same team let go of the rope at the same

time and quit playing. Which will most likely occur next?

• The rope will split into two pieces.

• The teams will move toward each other.

• The rope will move in the direction of the team with less members.

• The rope will move in the direction of the team with more members.

A truck is traveling in a straight line at a constant speed. Which could

cause it to move faster?

• a change in the mass of the truck

• a change in the volume of the truck

• a change in gravity acting on the truck

• a change in the force acting on the truck

Two dogs are pulling on a toy in opposite directions. Which could cause

the toy to move in a specific direction?

• if there is no friction acting on the toy

• if there is no gravity acting on the toy

• if the dogs keep pulling with the same amount of force

• if one dog begins pulling with a greater amount of force

Which will happen to a object moving at a constant speed if additional

force is applied to it in the same direction?

• It will change speed.

• It will increase in mass.

• It will decrease in mass.

• It will keep moving at the same speed.

Carli is trying to determine if a force can change the direction of an

object’s motion. The answer to which question will best help her come to

a conclusion?

• What happens when a ball rolls down a hill?

• What happens when a bat is used to hit a ball?

• What happens when a moving wagon comes to a stop?

• What happens when a person pushes on a large brick wall?

If a small rock and a large rock are both thrown at a wall at exactly the

same speed, which rock would most likely cause more damage to the

wall?

• The large rock would cause more damage because the force would be

  spread out on a larger area.

• The large rock would cause more damage because it has a greater

  mass, making the momentum greater.

• The small rock would cause more damage because it has a smaller

  mass, making the momentum greater.

• The small rock would cause more damage because all of the force

  would be concentrated on one small area.
