What force does a chair provide when you sit on it?

• Tension force

• Gravitational force

• Frictional force

• Normal force

What happens if a table cannot provide the required normal force to balance an object placed on it?

• The table will break

• The object will move sideways

• The object will float

• The object will stay in place

What is a normal force?

• A force that pulls objects down

• A force that moves objects sideways

• A force that holds objects up

• A force that opposes friction

What happens to the normal force if additional force is applied to an object?

• It increases

• It remains the same

• It decreases

• It becomes zero
