Understanding Forces in Physics

What is an example of a non-contact force?

• The gravitational pull between the Earth and the Moon

• The force between a chair and a person sitting on it

• The tension in a rope holding a swing

• The friction between a car's tires and the road

Which question helps identify non-contact forces acting on an object?

• Is the object moving at a high speed?

• Is there a planet, charge, or magnet nearby?

• Is the object in a vacuum?

• Is the object made of metal?

What type of force is present when two surfaces are pressed together?

• Tension force

• Normal force

• Magnetic force

• Air resistance

What is the force called when a stationary object is trying to move but is held back by friction?

• Sliding friction

• Static friction

• Air resistance

• Tension force

Which force is considered a catch-all type for any unaccounted push or pull?

• Gravitational force

• Tension force

• Applied force

• Normal force
