force unit
force
push or pull
contact
object touch
field force
act around an object (gravity and magnetism
newtons
newtons laws
2nd
the acceleration depend on two varibol, net force and object mass
3rd
For every action there is an equal and opposite reaction
1st
an object at rest stays at rest. a object in motion stays in motion
3 ways to accelerate
speed up
Slow down
Change direction
speed
distance/time
measured in miles per hour
distance
mass/volicty
measured in meters
Momentum
umph behind an object
Conservation
moved from object to object but not lost
time
distance/speed
gravity
the force that hold everything down to earth
momentum
mass x volicty
friction
a force between two objects that are touching and it acts object and it acts opposite to the motion
mass
kg
delta
Delta=change in △
projectile
an object that is thrown or shot through the air
force unit
Curved Path
Gravity pulling down
Trajectory
projectiles path
Inertia
The tendency of an object to resist changes in motion (the more mass the more interia)
