In one-two sentences outline how you could test the effect of gravity on object with different masses
3 answers
To test the effect of gravity on objects with different masses, you could drop the objects from the same height and measure the time it takes for each object to reach the ground, noting any differences in their falling speeds.
In 1-2 sentences explain why two object with the same mass when dropping the same, he may not reach the ground at the same time
Two objects with the same mass may not reach the ground at the same time when dropped simultaneously due to differences in their air resistance or shape, which can affect the rate at which they experience gravitational acceleration.
