Gravity
What is Newtons?
Positive and Negative.
What are two types of electric charge?
What is W=Fd?
A train is moving at the same speed as a car driving on a nearby road at 30 mph. The train will have more of this than the car.
What is momentum?
A push or a pull.
What is a force?
The rate at which gravity causes objects to accelerate.
9.8 m/s2
Two objects are rubbed together causing an electrostatic charge.
What is charging by friction?
The formula for gravitational potential energy.
What is PE=mgh?
The formula for momentum.
What is p = mv.
The force that keeps us grounded.
What is gravity?
Gravity causes this to occur between two masses.
What is an attractive force?
Transfer of charge by touching one object to another.
What is conduction?
Fd=mgh=1/2mv2
What is energy conservation?
What is J = Ft?
The force that causes clothes in the dryer to stick together.
What is electrostatic?
The formula for Newton's Law of Gravitation.
F=Gmm/d2
Causing an electrostatic charge without contact.
What is induction?
Mrs. Jamieson does 1200 J of work lifting a book up on the shelf. This is the total kinetic energy the book will have if it falls off the shelf.
What is 1200 J?
Mrs. Jamieson fell down on her skis. Her change in momentum was equal to this.
What is the impulse?
The unit of measurement for Force.
What are Newtons?
The gravitational force between the Earth and the Moon. The Earth is 5.972*1024 kg. The moon is 7.35*1022 kg. The distance is 3.84*109 m.
What is 2*1020 N?
Electrostatic forces have a magnitude and direction.
What is a vector?
My KE riding a bike at 3 m/s if the combined mass of myself and the bike is 85 kg.
What is 382.5 J?
Mrs. Jamieson has a mass of 65 kg and is walking at 1.5 m/s. This is her momentum.
What is 97.5 kg m/s?
These are the four fundamental forces of nature.
What is gravity, electromagnetism, weak nuclear force, strong nuclear force?
