Flashcards in Equations Deck (11):
1

weight = mass × gravitational field strength g

W=mg

2

work done = force × distance along the line of action of the force

W=Fs

3

Force applied to a spring = spring constant × extension

F=ke

4

distance travelled = speed × time

S = vt

5

acceleration = change in velocity / time taken

a=∆v / t

6

Resultant force = mass × acceleration

F=ma

7

momentum = mass × velocity

P = mv

8

kinetic energy = 0.5 × mass × speed 2

E k = 1/2 m v 2

9

gravitational potential energy = mass
× gravitational field strength g × height

Ep = m g h

10

power= energy transferred / time

P = Et

11

Power= work done / time

P = W/t
