This lesson

• Finishing §2.3
• Finishing §2.4 + 2.5
• Exersices

Goals 

• You know Hooke's law
• Understanding the spring constant
• to know and apply F= m x a
• Centripital force

Hooke's Law

Force = spring constanat x extension

F=k⋅x

(N)

(N/m)

(m)

Hooke's Law

Exersise

Rewrite the formula to calculate

• the spring constant
• The exentsion

F=k⋅x

A stiffer spring 

What does that mean?

A stiffer spring

Has a higher spring constant

What is resultant force?

What three things can a resultant force do?

What does this formula tell us?

F=m⋅a

Centripital force
