Equations

Question 1

What is the equation for acceleration

Answer 1

A = V-U / T

Acceleration = Final Velocity - Start velocity / time taken to change

Question 2

What is the equation for weight?

Answer 2

W= m x g

Weight = Mass x gravity

Question 3

What is the equation for mass?

Answer 3

M= w / g

Mass = weight / gravity

Question 4

What is the equation for Gravity?

Answer 4

G= w / m

Gravity = weight / mass

Question 5

What is the equation for force?

Answer 5

F = m x a

Force = mass x acceleration

Question 6

What is the equation for mass?

Answer 6

M = F / A

Mass = force / acceleration

Question 7

What is the equation for force?

Answer 7

F = change in momentum / time

Question 8

What is the equation for momentum?

Answer 8

M = m x v

Momentum = mass x velocity

Question 9

What is the equation for work done?

Answer 9

W = f x s

Work done = force x displacement

Question 10

What is the equation for power?

Answer 10

P = e / t

Power = energy transferred / time

Question 11

What is the equation for gravitational potential energy?

Answer 11

Gpe = m x gfs x height

Gravitational potential energy = mass x gravitational field strength x height

Question 12

What is the equation for kinetic energy?

Answer 12

Ke = 1/2 m x v(2)

Kinetic energy = 1/2 mass x velocity squared

Question 13

What is the equation for thermal energy?

Answer 13

Change in energy = mass x Specific heat capacity x temperature change

Question 14

What is the equation for specific heat capacity?

Answer 14

SHC = change In energy / mass x temperature change

Question 15

What is the equation for efficiency?

Answer 15

Efficiency = useful energy output / total energy input x 100

Question 16

What is the equation for elastic energy?

Answer 16

F = ke

Force = Spring constant x extension
