The property of an object to resist changes in motion

Newtons 2nd law

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 

300

Every force has an equal force in the opposite direction

Newtons 3rd law

300

speed at which an object travels in a given direction

Velocity 

300

The overall force on an object when all the individual forces acting on it are added together.

What controls the strength of the gravitational force between two objects?



Mass of each object and the distance between them

500

velocity divided by time equals ?

Acceleration 

500

 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
