the amount of space between two things
distance
how fast you travel
speed
the measurement of change in velocity during a period of time
acceleration
the law of inertia is
Newton's 1st law
mass is the measurement of
inertia
the movement of something from its position
displacement
speed in a given direction
velocity
positive acceleration is when an object
speeds up
the law of momentum is
Newton's 3rd law
the formula for momentum is
P=ma
used in most places around the world so scientists can share data without vocabulary confusion
SI (International System)
metric unit of speed
m/s, kph, etc
negative acceleration is when an object
slows down
F=ma is
Newton's 2nd law
the force required to accelerate an object with a mass of 1 Kg 1 meter per second per second
1 Newton
the process of changing postition
motion
formula for distance
speed times time
zero acceleration is when an object
has constant or no speed
a force that resists two surfaces that are touching
friction
momentum changes when what two things change
velocity
a complete description of your position includes what three things
1. distance
2. direction
3 reference point
vectors have what two things
magnitude and direction
acceleration can be what three things
1. change in speed
2. change in direction
3. change in speed and direction
the sum of all the forces acting on an object
net forces
the amount of momentum remains constant is called
conservation of momentum
