Terminal Velocity

What is terminal velocity?

The maximum constant speed a falling object reaches when air resistance equals the force of gravity.

What two main forces act on a falling object?

Gravity (pulling down) and air resistance (pushing up).

What happens when gravity and air resistance become equal during a fall?

The object stops accelerating and falls at a constant speed (terminal velocity).

What factors affect terminal velocity?

Mass, shape, surface area, and the density of the fluid it falls through.

Why does a parachute slow down a skydiver?

It increases air resistance, which lowers the terminal velocity.

Does all objects fall at the same terminal velocity?

No, terminal velocity varies depending on the object’s size, shape, and mass.
