Forces Flashcards
Newtons First Law
Law that states if the net force acting on an object is zero, the motion of an object does not change
Newton’s second law
Law that states that the acceleration of an object is equal to the net force exerted on the object divided by the objects mass
Newton’s third law
Law that states for every action there is an equal and opposite reaction
Potential energy
Stored energy due to the interactions between objects or particles
Kinetic energy
Energy due to motion
Rolling friction
Resistive force that slows down the motion of a rolling ball or wheel
Sliding friction
Opposes the motion of surfaces sliding past each other
Static friction
Prevents surfaces from sliding past each other
Fluid friction
Friction between a surface and a fluid
Centripetal acceleration
The idea that any object moving in a circle will have an acceleration vector pointed towards the center of that circle
Positive g’s
The G force exerted on the human body in a head ward direction during acceleration
Negative g’s
If you accelerate downwards faster than the rate of natural free falls
