Physics Fundamentals: Motion, Energy, and Momentum

Kinematics = Study of the motion of objects without considering the forces that cause the motion Dynamics = Study of the motion of objects and the forces that cause the motion Uniform motion = Constant velocity Force = Push or pull that causes an object to change its motion

Motion in One Dimension = Motion along a straight line Motion in Two and Three Dimensions = Motion in a plane or in space Projectile motion = Motion under the influence of gravity, with horizontal and vertical components Circular motion = Motion in a circular path, with constant speed and changing direction

Energy = Ability to do work Kinetic energy = Energy of motion Potential energy = Energy of position or stored energy Work = Transfer of energy from one object to another

<p>Momentum = Product of an object's mass and velocity Conservation of momentum = Total momentum remains constant in a closed system Elastic collisions = Collisions in which kinetic energy is conserved Inelastic collisions = Collisions in which kinetic energy is not conserved</p> Signup and view all the answers

<p>Newton's First Law = Law of Inertia: an object at rest remains at rest, and an object in motion remains in motion, unless acted upon by an external force Newton's Second Law = F = ma: the force applied to an object is equal to the mass of the object multiplied by its acceleration Newton's Third Law = Action and Reaction: for every action, there is an equal and opposite reaction Law of Conservation of Energy = Energy cannot be created or destroyed, only converted from one form to another</p> Signup and view all the answers

<p>Displacement = Change in position of an object Velocity = Rate of change of displacement with respect to time Acceleration = Rate of change of velocity with respect to time Gravity = g = 9.8 m/s^2</p> Signup and view all the answers
