|
||||
show | the amount of space between two points.
🗑
|
||||
show | the distance between the final and starting position
🗑
|
||||
Motion | show 🗑
|
||||
show | describes how fast something is moving (s= d/t)
🗑
|
||||
Velocity | show 🗑

Acceleration | show 🗑
|
||||
show | measures an object’s tendency to resist changing its motion. The more inertia an object has, the harder it is to start the object moving or to slow it down. Inertia depends on the amount of matter in an object, or its mass.
🗑
|
||||
show | is a contact force that resists motion between two touching surfaces

|
||||
show | a frictional force between air and objects moving through it
🗑
|
||||
show | is the pull that all matter exerts on other matter
🗑
|
||||
show | is the force of gravity on an object on the planet or moon where the object is. Weight is a force and is measured in Newton's
🗑
|
||||
show | is the amount of matter in an object
🗑
|
||||
Force | show 🗑
|
||||
show | a push/pull that one object applies to another object that is touching it.
🗑
|
||||
show | a force that one object applies to another object without touching it.
🗑
|
||||
Balanced Force | show 🗑
|
||||

|
||||
Newton's First Law of Motion- | show 🗑
|
||||
