Sir Isaac Newton: 2nd Law of Motion

Sir Isaac Newton2nd Law of Motion

Part 1:

Force in Star Wars

Part 2:

Acceleration Depends on Mass:-The bigger the mass, the more force you need to exert to accelerate (Vice versa)

- Born on January 4, 1643- Almost died as a baby, was premature- Went to college at Trinity, in Cambridge- He was a stutterer- The apple observation never happenend (Picture to right) - Predicted the world would end in 2060- Very religious- As a member in Parliament in 1689 for one year, Newton only muttered one sentence in his whole term and it was to close a window because it was cold- Had a nervous breakdown when he was older- In 1696 he was the Warden of the Royal Mint- Died March 31, 1727

Acceleration Depends on Force:-The harder/more force you put on an object, the more acceleration (Vice versa)

Background

Of Sir Isaac Newton

Less Mass

More Mass

Less Force

More Force

Pictures of Newton's 2nd Law: Equations

In Star Wars, Darth Vader needs to use more force to lift up someone who is more massive (bigger). Therefore he must use more energy in his hand/grip to strangle his enemy.

Like the other picture, this is the equations of how he proved that the bigger the mass, the more force you need to accelerate an object.

Also in the movie, many remember a famous quote relating to force/gravity. "Use the force Luke."

This is the math behind Newton's conclusion being that the more force you put on an object the more acceleration.

In the beginning, Mike kicks a ball with little to no force. As a result, the ball he kicked did not travel very far because it didn't have acceleration.

However, when we added Kyle to the chair, there was more and heavier mass. So Mike had to use more force to accelerate the more massive object.

Mike is pushing a chair that has nothing on it, therefore it has a low mass. He pushes it with barely any force needed.

When Mike puts more force on the ball by moving his leg back further and exerting more energy, the ball has more acceleration. That is why the ball travelled further.

Only if Sir Isaac Newton had an iPhone back then...
