What is required for an object to start moving?

• No force at all

• A balanced force

• A net force of zero

• An unbalanced force

What is net force?

• The strongest force acting on an object

• The combination of all forces acting on an object

• The total amount of force applied to an object

• The force that is not affected by gravity

What happens if the net force on an object is zero?

• The object will accelerate

• The object will not move

• The object will change direction

• The object will move faster

What is an example of a balanced force?

• Two people pushing a box with equal force from opposite sides

• A leaf falling from a tree

• A ball rolling downhill

• A car speeding up

How do unbalanced forces affect an object?

• They cause the object to remain still

• They cause the object to accelerate or change its motion

• They balance the object in mid-air

• They do not change the object's motion

What does it mean if two forces are opposing each other?

• They are moving in the same direction

• They always result in motion

• They cancel each other out

• They are both acting on different objects

How can you calculate net force when two forces act in opposite directions?

• By multiplying the forces

• By subtracting one force from the other

• By dividing one force by the other

• By adding the forces together
