What does freefall mean in physics?

• When an object is under the influence of multiple forces

• When an object is under the influence of only gravity

• When an object is stationary

• When an object is moving upwards

A ball is thrown upwards and caught when it comes back down at the same height. In the absence of air resistance, the speed of the ball when caught would be

• less than the speed it had when thrown upwards.

• more than the speed it had when thrown upwards.

• the same as the speed it had when thrown upwards.

• need more information to determine.
