Friction, Gravity and Energy
energy of motion
Kinetic energy
An object at rest stays at rest unless acted upon by an unbalanced force. An object in motion stays in motion unless acted upon by an unbalanced force
newtons 1st law
angle of a line on a graph
Slope
The state in which one object’s distance from another is changing
Motion
What is the correct order of the rainbow?
Red, Orange, yellow, green, blue, purple,
energy stored in an object
Potential energy
The property of an object to resist changes in motion
Newtons 2nd law
is the distance the object moves per unit of time
Speed
A push or pull exerted on an object.
Force
What season are we in?
fall
What the the types of friction?
Rolling Friction- When an object rolls across a surface
-a ball rolling across the floor
Sliding Friction- When two solid surfaces slide across each other
-Sliding a chair across the room
Fluid Friction- Occurs when a solid object moves through a liquid
-Fish swimming through a lake
Static Friction-acts on an object when they are resting on a surface
Trying to push a couch
Every force has an equal force in the opposite direction
Newtons 3rd law
speed at which an object travels in a given direction
Velocity
The overall force on an object when all the individual forces acting on it are added together.
Netforce
What are our school colors
blue and white
A smoother surface will produce less friction than rough surfaces
True or false
True
Resistance to change in motion
Force
distance divided by time equals?
Velocity/speed
More than one force can act on an object at a time.
True of False
True
What is Miss Maddy's favorite Coffee Flavor?
Carmel
What controls the strength of the gravitational force between two objects?
Mass of each object and the distance between them
velocity divided by time equals ?
Acceleration
Forces- applied only when objects touch another
Ex. you pushing a box across a floor, Friction
Forces- force applied whether it touches the object or not
Ex. Gravity, Magnetism, Electrical Forces
Contact, NON contact
What sport did Miss Maddy play in college?
Volleyball
