Unit 5 - Forces Equations

Question 1

How do we calculate Weight?

Answer 1

Weight = mass x gravitational field strength

Question 2

How do we calculate Work Done?

Answer 2

Work Done = force x distance ( moved along the line of action of the force )

Question 3

How do we calculate Force?

Answer 3

Force = spring constant x extension

Question 4

How do we calculate the Movement of a Force?

Answer 4

Movement of a Force = force x distance ( perpendicular to the direction of the force )

Question 5

How do we calculate Pressure?

Answer 5

Pressure = force normal to a surface / area of that surface

Question 6

How do we calculate Distance Travelled?

Answer 6

Distance Travelled = speed x time

Question 7

How do we calculate Acceleration?

Answer 7

Acceleration = change in velocity / time taken
Acceleration = final velocity - initial velocity / time taken

Question 8

How do we calculate Resultant Force?

Answer 8

Resultant Force = mass x acceleration

Question 9

How do we calculate Momentum?

Answer 9

Momentum = mass x velocity
