Darren from Kinetic is a graduate engineer and he’s showing us how gravity works! Gravity acts as a magnet pulling objects into the centre of Earth.
Galileo taught us a lot about gravity and Darren shows us what Galileo was talking about using a tennis ball, an apple and grapes.
No matter how heavy an object it is, generally everything takes the same amount of time to hit the ground. Sometimes air resistance comes into it though, like when a feather floats to the ground.
