Question 2

What is a force and what is the unit for force

Answer 2

A push or a pull or a twist. Newtons

Question 3

What force is going up

Answer 3

Support is keeping it stable

Question 4

What force is going down

Answer 4

Gravity is pushing object down

Question 5

What force is going left

Answer 5

Friction is acting against the movement of object

Question 6

What force is going right

Answer 6

Thrust is acting behind object

Question 7

The formula for force

Answer 7

F= Ma

Question 8

Energy law

Answer 8

Energy cannot be created or destroyed, you can only change it from one form to another

Question 9

What is the equation for speed

Answer 9

S= d/t

Question 10

What is the formula for gravitational potential energy

Answer 10

GPE=m x g x h

Measured in joules

Question 11

What is the formula for kinetic energy

Answer 11

Ek = 1/2 mv2

Measured in joules

Question 12

What is gravitational energy

Answer 12

Energy found high up like on a mountain

Question 13

Kinetic energy

Answer 13

Movement

Question 14

Rearranged kinetic formula to make velocity the subject

Answer 14

V= square root 2Ek/ m

Question 15

Work formula

Answer 15

W= fd

Question 16

Work

Answer 16

Done when energy is changed from one kind to another. Work is measured in joules

Question 17

Pressure concept

Answer 17

The smaller the area the more force in one area so more pressure exerted. The larger the area the force is spread out so less pressure is exerted in one area

Question 18

Pressure is measured in

Answer 18

Nm-2
