Newtons first law (inertia)
an object at rest stays at rest
Balanced forces
equal forces acting on an object
Force
a push or pull on an object
Friction
the force that a surface gives off when they come in contact
Acceleration
when a moving object speeds up
Newtons third law
every action has an equal reaction
Displacement
how far from original position it moves
Free fall
in physics this is a body of motion falling through the atmosphere
Rolling friction
the force that slows down a rolling object
Average speed
the overall rate of speed an object moves
Newtons law of universal gravitation
a particle attracts all other particles but the strength is dependant on the distance
Energy
the ability to do work
Gravity
the force that pulls all object towards earths center
Sliding friction
occurs when two objects slide off each other
Motion
the state in which one objects distance from another is getting closer or farther
Sir Isaac Newton
Developed laws of motion
Reference point
a object used to compare if an object moves
Mass
the amount of matter in an object
Static friction
comes into play when a body is forced to move along a surface but movement doesn't start
Terminal velocity
the greatest velocity a falling object can achive
Newtons second law
force=mass*acceleration
Speed
the distance an object moves per unit
Momentum
the product of an objects mass and velocity
Fluid friction
when an object moves through or in the air then exists a resistive force
Velocity
speed in a giving direction
