Question 1

Mass.

Answer 1

The amount of matter in a substance (KG) remains constant in any gravity

Question 2

Weight

Answer 2

In newtons, how an object’s mass is affected by gravity. Weight (N) = mass x 9.81

Question 3

Force

Answer 3

Can change the speed of an object, the direction it’s going in, or it’s shape.
Force (N) = mass (KG) x acceleration (m/s squared)

Question 4

Downwards acceleration from gravity

Answer 4

9.81 m/s squared

Question 5

Momentum

Answer 5

The tendancy of an object to keep moving in the same direction.
Momentum ( KG m/s) = Mass (KG) x velocity (m/s)

Question 6

Force in relation to momentum

Answer 6

Force = change in momentum/ time taken

Question 7

Force applied (to a spring) =…

Answer 7

Force applied (N) = spring constant N/m x exetnsion
