Forces Quiz

What is a balanced force?

• A single force acting on an object

• No forces acting on an object

• Two unequal forces acting in the same direction

• Two equal forces acting in opposite directions

Provide an example of a balanced force.

• A car accelerating on a straight road

• A person lifting a heavy object off the ground

• A rocket launching into space

• Two people of equal strength pushing against each other with the same force.

How would you define an unbalanced force?

• An unbalanced force is a force that keeps an object at rest.

• An unbalanced force is a force that only affects the shape of an object.

• An unbalanced force is a force that causes a change in the motion of an object.

• An unbalanced force is a force that has no effect on an object's motion.

Can you give an example of an unbalanced force?

• A person pulling a box with equal force on each side.

• A car moving at a constant speed on a straight road.

• A book resting on a table.

• A person pushing a box with unequal force on each side.

Explain how to calculate the net force when forces are balanced.

• The net force is negative

• The net force when forces are balanced is zero.

• The net force is always positive

• The net force is doubled

Describe a scenario where balanced forces are at play.

• A person lifting a heavy object off the ground

• A car accelerating on a straight road

• Two magnets attracting each other

• Two people pushing against each other with equal force

In what situations do unbalanced forces occur?

• Unbalanced forces occur when the object is in equilibrium.

• Unbalanced forces occur when the forces are equal in magnitude and opposite in direction.

• Unbalanced forces occur when the net force acting on an object is not zero.

• Unbalanced forces occur when the object is at rest.

Give an example of a common unbalanced force in everyday life.

• Sliding a book across a table

• Pushing a car

• Lifting a weight

• Pulling a heavy object with a rope

Calculate the net force when a 10N force acts to the right and a 5N force acts to the left.

• 15N

• 2N

• 5N

• 7N

If a 20N force pushes an object to the right and a 15N force pushes it to the left, what is the net force?

• 35N

• 5N

• 10N

• 25N
