|---|---|---|---|---|---|
| Speed | Speed is the change in distance over a specific amount of time.
🗑
|
||||
| Speed Formula | Speed = distance
divided by time
s = d/t
🗑
|
||||
| Velocity | Velocity is speed in a given direction
🗑
|
||||
| Acceleration | Change in speed or velocity over a specific amount of time,
Speeding up, slowing down, change in direction
🗑
|
||||
| Balanced Forces | Two forces equal in size and acting in opposite directions on an object. No movement
🗑
|
||||
| Unbalanced Forces | Two forces that are unequal in size and opposite in direction.
Movement.
🗑
|
||||
| Net Force | The overall forces acting on an object.
Measured in Newtons (N)
🗑
|
||||
| Force | A push or a pull on an object
Causes a change in the motion of an object
A object’s mass multiplied by acceleration (F=ma)
🗑
|
||||
| Friction | The force that causes a moving object to slow down when it touches another object.
One object rubbing against another
🗑
|
||||
| Applied Force | A force that is applied to an object by a person or another object.
Ex. – A person pushing a box up a ramp
Ex. – A bulldozer moving dirt
🗑
|
||||
| newton's first law of motion | an object at rest will stay at rest AND an object in motion will stay in motion UNLESS an outside force acts on it
🗑
|
||||
| newton's third law of motion | for every action, there is an equal an opposite reaction
🗑
|
||||
| newton's second law of motion | the greater the mass of an object, the greater the force needed to accelerate that object
🗑
|
||||
| law of conservation of mass | mass is neither created nor destroyed; we can demonstrate this with a balanced equation
🗑
|
||||
| gravity | the force that pulls all objects towards the center of a planet
🗑
|
||||
| kinetic energy | energy of motion
🗑
|
||||
| potential energy | stored energy
🗑
|
||||
| density formula | D= M/V
🗑
|
||||
| Simple Machines | A simple device for changing the amount or force or
direction of force to move an object.
🗑
|
||||
| Formula for Work | W = f x d
Work = force times distance
🗑
|
||||
| Newton | The SI unit for force (Symbol, N)
🗑
|
||||
| Motion | An object's change in position relative to a reference point
🗑
