Forces And Elasticity

Question 1

Describe the conversion of energy when force is applied to an elastic object.

Answer 1

> work is done to change the shape of an object, converted and stored as elastic potential energy

> when the force is removed the energy is converted back into kinetic energy, causing the object to turn back to its original shape

Question 2

What is the limit of proportionality?

Answer 2

The maximum force that an elastic object can take and still extend proportionally

Question 3

What happens if you increase the force on an elastic object past the limit of proportionality?

Answer 3

> the object will be permanently stretched

Question 4

What is an elastic object?

Answer 4

An object that can revert back to its original shape after a force has been applied to it.
