|---|---|---|---|---|---|
| definition of force | a push or pull. when one object pushes or pulls another object the first object exerts a force on the second object
🗑
|
||||
| definition of friction | the force that 2 surfaces exert on each other when hey rub against eachother
🗑
|
||||
| definition or mass | the amount of matter in an object
🗑
|
||||
| definition of weight | the force of gravity acting on an object
🗑
|
||||
| state the law of universal gravitation | the force of gravity between all objects in the universe have mass
🗑
|
||||
| definition of gravity | a force that pulls objects towards eachother
🗑
|
||||
| what happens when 2 forces are in the same direction | the object they're putting the force on will move in the same direction as the force
🗑
|
||||
| how does mass affect inertia | the greater the mass of an object the greater its inertia and the greater force required to change its motion
🗑
|
||||
| what is newtons first law of motion. example | an object a t rest will stay at rest an object in motion unless acted upon by an nonzero force will stay in motion unless acted upon by an nonzero net force. a falling book hits the floor
🗑
|
||||
| what is newtons second law of motion. example | an objects acceleration depends on its mass and net force acting on it. pushing full shopping carst vs. empty shopping cart.
🗑
|
||||
| what is newtons third law of motion. example | if one object exerts a force on another object then the second object exerts a force of equal strength in the opposite dirrection of the first. laying in bed
🗑
|
||||
| how does mass affect gravity | the more mass the greater the gravitational force between it and other objects
🗑
|
||||
| what is net force | the combination of all the forces on an object
🗑
