Physics Intro


Force Any interaction which tends to change the motion of an object - a push or pull.
Applied Force a force that is applied to an object by a person or another object
Friction Force the force exerted by a surface as an object moves across it or makes an effort to move across it
Newton Forces are measured in this SI unit and represented by the symbol N
Vector a quantity that has both magnitude and direction.
Magnitude the absolute "size" of a quantity, ignoring other details like direction.
Displacement shortest distance between the initial point and final point of an object - often confused with simple distance.
Velocity the rate at which an object changes its position (speed and direction)
Acceleration the rate at which an object changes its velocity - in either a positive or negative change
Equilibrium When all the forces that act upon an object are balanced (does not mean they are equal to each other).
