Science #3

What will most likely be the outcome of this collision?

• Vehicle A will have no change in speed and be pushed to the left because it has a smaller mass.

• Vehicle A will have a change in speed and be pushed to the left because it has a larger mass.

• Vehicle B will have no change in speed and be pushed to the left because Vehicle A has a larger mass.

• Vehicle B will have a change in speed and be pushed to the right because Vehicle A has a larger mass.

If a student exerted a force of 1 N towards the north, what would be the effect on the speed and direction of the marble?

• The speed of the marble would be unchanged, and the direction would change to the northeast.

• The speed of the marble would decrease, and the direction would change to the northwest.

• The speed of the marble would increase, and the direction would change to the northwest.

• The speed of the marble would decrease, and the direction would change to the north.

Which of the following statements best explains the data collected by the student shown in the above table?

• The speed of the toy car increases due to forces greater than gravity.

• The speed of the toy car decreases due to balanced forces.

• The speed of the toy car increases due to unbalanced forces.

• The speed of the toy car decreases due to friction.

One of the laws of motion states, "An object in motion stays in motion unless an unbalanced force acts upon it." On Earth, objects always seem to eventually come to a stop when more force is not being applied.

What force is causing the objects to eventually stop moving?

• Mass

• Friction

• Weight

• Gravity

According to the above information and diagram, what will be the result?

• The box will move to the right with an 8 N force.

• The box will move to the right with a 24 N force.

• The box will move to the left with a 2 N force.

• The box will move to the left with an 8 N force.

In which direction will the center of the rope go?

• to the west because the net force is greater in this direction

• to the east because the net force is greater in this direction

• to the west because the net force is less in this direction

• to the east because the net force is less in this direction
