Physics = Pressure Level 1

Which equation is the correct one used to calculate pressure?

• P = W x d

• p = m x v

• P = W x A

• P = F / A

How do you calculate the area of an object?

• 
• 
• 

Calculate total area of the skis. Length is 1.2 m and width is 0.07 m

• 1.2 +1.2+ 0.07 + 0.07 = 2.54 m ²

• 1.2 x 0.07 =0.084 m ²

• 1.2 x 0.07 = 0.084 x2 =0.168 m ²

• 1.2 x 0.07 x 0.07 = 0.91 m ²

Bob's car has 4 tyres. Each tyre is 0.205 m wide and 0.506 m long. Calculate the total area of all the tyres on the road.

• 0.205 + 0.506 = 0.711 m ²

• 0.205 x 0.506 = 0.104 x 4 = 0.415 m ²

• 0.205 + 0.506 = 0.711 x 2 = 1.42 m ²

• 0.205 x 0.506 = 0.104 m ²

An objects mass can be converted into weight force. Which equation do you use to do this?

• F = w x d

• E_p = mgh

• F = mg

• F = P x A
