Mass and weight

Question 1

If we ignored air resistance

What would happen when we drop a ball to the ground

Answer 1

The ball would accelerate constantly.

Question 2

For IGCSE

What is acceleration of free fall (2.SF)

Answer 2

9.8 m/s^2

Question 3

For IGCSE

What is acceleration of free fall (2.SF)

Answer 3

9.8 m/s^2

Question 4

What happens when a skydiver falls towards the earth from a great height

Answer 4

He would constantly accelerate until he reaches terminal velocity when the air resistance balances the gravities force
