Newton and His Laws
Newton's 1st Law of Motion
A push or pull on an object.
What is force?
Someone from 1st hour leaves their breakfast scraps on the table until Ms. Pfrommer picks it up later.
Newton's 1st Law. An object at rest stays at rest.
On the way to work, Ms. Pfrommer saw a Maserati driving in DeKalb. The driver of the Maserati is able to go 320 kilometers in 2 hours. What is the speed of the car?
What is 160 kph
This is the formula for finding force
Mass x Acceleration
Force = Mass x Acceleration is which law?
What is Newton's 2nd Law.
How fast or slow something is moving.
What is speed?
You are able to push your little cousin in a wagon easier than you can push your friend in the wagon.
Newton's 2nd Law Force = Mass x acceleration
A boy kicks a .445 kg soccer ball with a force of 75 Newtons. What is the acceleration?
168.5 m/s
Distance over Time will find what?
Speed
For every action there is an equal and opposite reaction.
What is Newton's 3rd Law.
Velocity is different from speed because it takes into account this.
What is the direction of travel?
During tipoff, two players knock into each other and both fall backwards.
Newton's 3rd Law. Equal and opposite reaction
A ladybug travels 5 cm in 2.5 seconds. What is the average speed.
What is 2 cm per second.
This is the name of the unit used when finding the mass of an object.
What is a Newton (N)
This law of motion states that the acceleration of an object equals the net force acting on the object divided by the object's mass.
Newton's 2nd Law
Friction and gravity can be examples of what type of force?
What is an unbalanced force?
Your body jolts forward when a car abruptly stops.
Newton's 1st Law. An object in motion will stay in motion. An object at rest will stay at rest.
A baseball is thrown a distance of 20 meters. What is the speed if it takes 0.5 seconds to cover the distance?
What is 40 m/s
Force over acceleration will find what?
What is mass.
This law is sometimes called the Law of Inertia
What is the 1st Law
This is an object's tendency to resist change
What is inertia?
When thrown with the same force, a 12 pound bowling ball accelerates faster than an 8 pound bowling ball.
What is Newton's 2nd Law.
Using the second law of motion, it takes 5100 N of force to accelerate a car 3 m/s squared. What is the mass of the car.
When finding force, you use this unit in your answers.
What is meters per second squared.
m/s 2
