Define elastic object
Its a shape that regains it shape when the force deforming it is removed. When it is deformed the energy stored is called elastic energy.
Define compression
When a force is exerted on an object it will compress.
Define tension
This is when a force pulls on an object.
Explain what happens to the particles in compression and tension
In compression the particles are pushed closer but in tension it is pushed away.
What is hooke’s law
The extension of a spring is the directly proportional to the force applied.
Whats the equation for hooke’s law
Force applied = spring constant x extension
F(N) = K(N/m) x X(m)
What does spring constant measure
How stiff the spring is. The larger the spring constant the stiffer the spring
What is spring constant measured in
-1
Nm
