Understanding Balanced and Unbalanced Forces

What is the net force when forces are balanced?

• Equal to zero

• Cannot be determined

• Less than zero

• Greater than zero

What happens to an object's motion when the net force is zero?

• It accelerates

• It decelerates

• It changes direction

• It remains constant

Which force opposes the motion of a box being pushed on the floor?

• Gravitational force

• Magnetic force

• Normal force

• Frictional force

If a box is pushed with a force greater than friction, what will happen?

• The box will float

• The box will stay still

• The box will move

• The box will move in the opposite direction

In a system with 25 N left and 15 N right, what is the net force?

• 10 N to the right

• 10 N to the left

• 40 N to the right

• 40 N to the left

In a tug of war, if one side pulls with 30 N and the other with 10 N, what is the net force?

• 20 N to the stronger side

• 40 N to the weaker side

• 20 N to the weaker side

• 40 N to the stronger side

What is the net force when two friends push a table with 20 N and 15 N to the right?

• 35 N to the left

• 5 N to the left

• 35 N to the right

• 5 N to the right

What does a positive net force indicate about the direction of motion?

• Motion in a circular path

• Motion to the left

• Motion to the right

• No motion

What is the result of unbalanced forces acting on an object?

• Object moves in a circle

• Object remains stationary

• Change in motion

• No change in motion

How can you determine the net force in a system?

• By adding the forces

• By subtracting the forces

• By multiplying the forces

• By dividing the forces
