Issac Newton and His Laws of Motion
BY: Mona ChiangPowerpoint created by Chikila Moore
Introduction
• Why does the ball always bounce back after it hits the floor?
• Why can’t I jump so high that I fly above the hoop?
• Newton’s laws use math to explain how everything moves.
Who Was Newton?
• Newton’s father died 3 months before he was born.
• His mom married a rich preacher.
• He was sent away to his grandparents and to school.
• His father was a farmer who could not read or write.
• Issac’s teacher put him a the bottom of his class but he soon became a top student.
Man of Many Sciences• Newton made key discoveries.• Newton studied what other
scientist had learned about this.
• This law explains that all objects in the universe have gravity.
• Newton was the first to recognize that the force holding an object to earth is the same as the force holding the moon.
• He used his knowledge of optics to build a powerful telescope.
First Law of Motion
• Our push is the force that makes a ball move.
• A scientists named Galieo Galilei conducted many experiments to test new ideas.
• He studied Galieo Galilei’s work on motion.
First Law In Action
• Something needs force to move.
• Something has to keep moving at the same speed.
• Friction is a force that occurs whenever two objects rub against each other .
• This soccer ball has friction.
Other Forces
• The force of gravity pulls the ball down.
• Newton’s first law applies to more than soccer.
• What force or forces might cause those change?
First Law and Space Travel
• Friction and gravity affect just about every object on earth.
• Outer space has no air particles to cause friction.
• Only a force such as the firing of rocket engines.
Inertia
• Newton’s first law shows that an object will not change its motion.
• An object resists any change in motion.
Acceleration
• Acceleration is how fast an object changes speed or direction or both.
• You can accelerate when you turn the corner because you change direction.
Math Behind The Law
• The second law of motion shows how force , mass , and acceleration are related or connected
force=mass*acceleration.
Units of Force
• Every measurement includes a number and a unit. Units are called newton’s named after Issac.
Newton’s Third Law of Motion
• The third law of motion means that forces always act in pairs.
• When one object exerts a force on another object.
The Third Law In Action
• You move toward the desk. You pulled on the desk and the desk pulled on you in the opposite direction.
Conclusion
• Today , engineers use these laws to determine how much force is needed to boost a rocket into space.
• His laws are to design many things. Machines could not have been invented without understanding the laws of motion.
When year was Issac Newton born?
• 1)1964• 2)1642• 3)2020• 4)1968
How did Issac’s father die?
• 1)you don’t know.• 2)he died in a car
accident.• 3)somebody shot him
