Spring Loaded Physics

When does the spring force appear?

• The spring is compressed or stretched (deformed).

• The spring is compressed

• The spring is stretched

• Always

Where is the spring force acting on?

• the spring.

• the object that causes the spring to deform.

• hand

• the wall

What is the direction of the spring force?

•  inwards the spring.

• toward the outside of the spring.

• perpendicular to the spring axis.

• is always in the opposite direction of the external force causing deformation.

If F is force, k is spring constant and x is extension, Hooke's Law tells us that:

• F=k/x

• x=Fk

• k=Fx

• F=kx

The spring constant of an object tells you?

• What type of spring you are dealing with

• How long the spring will stretch or compress

• It gives you a value on how easy or hard it is to change the objects length.

• A spring constant gives you a number which tells you what material the spring is made of.

Which is the unit of the spring constant.

• m

• N

• N/m

• N.m

Which is the unit of the displacement of the spring

• m

• N

• N/m

• N.m

Hooke's Law fails when a material reaches its:

• breakdown

• elastic limit

• end of tether

• fracture stress

What is the extension of the spring?

• 3cm

• 4cm

• 7cm

• 11cm

What is the original length of the spring?

• 3cm

• 4cm

• 7cm

• 11cm
