Forces and Motion Quiz

When two forces act in the same direction on an object, how do you calculate the net force?

• Subtract the smaller force from the larger force

• Add the two forces together

• Multiply the two forces

• Divide the larger force by the smaller force

According to Newton's third law of motion, if object A exerts a force on object B, what does object B do?

• Exerts a force of equal magnitude in the same direction on object A

• Exerts no force on object A

• Exerts a force of equal magnitude in the opposite direction on object A

• Instantly stops moving

In a force diagram, what does an arrow represent?

• The mass of the object

• The direction and magnitude of a force

• The speed of the object

• The friction acting on the object

What type of force opposes the motion of objects sliding against each other?

• Gravity

• Magnetic force

• Friction

• Air resistance

If an object is moving to the right with a force of 5 N and there is a frictional force acting to the left with a magnitude of 3 N, what is the net force?

• 2 N to the right

• 2 N to the left

• 8 N to the right

• 8 N to the left

When the net force on an object is zero, what can we say about the object's motion?

• The object is accelerating

• The object is moving at a constant velocity

• The object is slowing down

• The object is not moving

What does it mean for forces to be unbalanced?

• The forces are all acting in the same direction

• The forces are equal in magnitude but act in opposite directions

• The forces result in a net force of zero

• The forces result in a net force that is not zero

• 5 N to the left

• 25 N to the right

• 25 N to the left
