What is elastic deformation?
A spring is stretched so much that it cannot return to its original state
When an elastic is stretched so much that it breaks
When anything that can stretch is stretched so much that it is stuck at an extended extention
An elastic stretched then eventually returns to its original shape
What is the equation for power?
(a)
How much Power does Timmy use if he transfers 1080J in 15 minutes?

What is Newton's third law?
The force is the product of the mass and acceleration
If the resultant force is 0, the velocity remains the same
If the resultant force is not 0, the velocity stays the same
Everything exerts equal and opposite forces
