1678, Robert Hooke: first good model for the force that a spring exerts.

1.5.2 Plot and interpret extension–-load graphs and describe the associated experimental procedure

• This is a spring

​

• A spring will stretch (extend) when a force is applied and return back to its original shape.

​

• We can predict how far the spring will go using Hooke’s Law

​

• Different springs have different ‘springy-ness’ called a spring constant

1. Calculate your force in N
2. Calculate the extension on the spring for numerous intervals
3. Plot these on a graph (extension on y axis)

1678, Robert Hooke: first good model for the force that a spring exerts.

1.5.2 Plot and interpret extension–-load graphs and describe the associated experimental procedure

• Proportional means that two amounts change at the same rate so that the relationship between them does not change.
• When force increases, extension increases at the same rate. This is called Hooke’s Law.
• The formula for Hooke’s Law is
• f = - kx
• F = Force(N), K = Spring Constant (N/m), x = extension (m)
• When force and extension are no longer proportional, the spring has become deformed.

What is Hooke’s Law?

1.5.3 State Hooke’s law and recall and use the expression F = k x, where k is the spring constant

If the force applied is doubled, the spring with extend double.

If the force applied is directly proportional to the spring extension

1.6.1 Relate qualitatively pressure to force and area, using appropriate examples

P1 Motion

Pressure on solids is caused by the weight of the object pushing down on the solid over a given area

1.6.1 Relate qualitatively pressure to force and area, using appropriate examples

The units of pressure depend on the units of area:

If the area is measured in cm² (and the force in N), then the pressure will be in N/cm²

If the area is measured in m² (and the force in N), then the pressure will be in N/m²

Pressure can also be measured in pascals, Pa�1 Pa is the same as 1 N/m²

Eg1. A mouse exerts 500 N of force over an area of 10 m². Use the formula to calculate the pressure.

Pressure = Force/Surface area

Pressure = 500N/10m²

Pressure = 50N/m²

P1 Motion

1.6.2 Recall and use the equation p = F /A

Eg2. A mouse exerts 800 N of force over an area of 16 m². Use the formula to calculate the pressure.

Pressure = Force/Surface area

Pressure = 800N/16m²

Pressure = 50N/m²

P1 Motion

1.6.2 Recall and use the equation p = F /A

Eg3. A ballerina exerts 60 N of force over an area of 0.02 m². Use the formula to calculate the pressure.

Pressure = Force/Surface area

Pressure = 60N/0.02m²

Pressure = 3000 N/m²

P1 Motion

1.6.2 Recall and use the equation p = F /A

Eg4. A truck exerts 800 N/m² of pressure over an area of 8 m². Use the formula to calculate the force

Force = 6400 N

F = P x A
