Hooke’s Law and Pressure

Question 1

What is the equation for Pressure?

Answer 1

P = F/A

Question 2

What is weight?

Answer 2

A force

Question 3

If there is less area then what happens to the pressure?

Answer 3

It increases

Question 4

What is Hooke’s Law?

Answer 4

That the force applied is directly proportional to the extension of the spring

Question 5

What is the unit for pressure?

Answer 5

Pa

Question 6

What is the unit for force?

Answer 6

Newtons / N

Question 7

Does the line of best fit apply to a Spring extension graph or an Elastic band extension graph?

Answer 7

Spring graph

Question 8

If there are two holes at equal height on a can, then is there a difference in pressure from the water in both holes?

Answer 8

No

Question 9

Why do objects implode?

Answer 9

Because the pressure on the outside is greater than the pressure on the inside

Question 10

How can pressure be increased?

Answer 10

A. Increasing the number of particles
B. Reducing the size of the container
C. Increasing the temperature of the particles

Question 11

What happens if there are more particles in the balloon?

Answer 11

The particles will have more collisions with the wall of the balloon therefore causing more force to be exerted on the inside wall

Question 12

What can will have more pressure in - the one with 10 particles or 20 particles?

Answer 12

20 particles

Question 13

What is liquid pressure?

Answer 13

The pressure produced by collisions of particles in a liquid

Question 14

Does the force of a foot stay the same when the area of the object stepped on increases or decreases?

Answer 14

Yes

Question 15

What happens when the area is increased?

Answer 15

The pressure is decreased

Question 16

What does the line on a spring graph look like?

Answer 16

A straight line

Question 17

What happens when a spring passes it’s elastic limit?

Answer 17

It can no longer spring back to its original length
