Physics Review Personal

the total length of the path traveled by an object; a scalar quantity

the change in position of an object from its initial position to its final position; a vector quantity

physical quantities that have only magnitude and no direction

physical quantities that have both magnitude and direction

the location of an object relative to a chosen reference point

speed is a scalar quantity that refers to how fast an object is moving, velocity is a vector quantity that refers to the rate at which an object changes its position

the rate of change of velocity with respect to time; a vector quantity

when an object's acceleration is constant over time

when an object's acceleration changes over time

a special case of uniform acceleration where an object is falling under the influence of gravity

the motion of an object moving in a circular path at a constant speed

although the speed may be constant, the velocity is not because the direction is always changing meaning that the velocity is always changing

the force that acts on an object moving in a circular path, directed towards the center of the circle; keeps the object moving in a circular path; F=mv^2 / r

what turns the velocity vectors to keep the object traveling in a circle; ac= v^2 / r

the force of attraction between two masses; F=G(m1m2) / r^2

6.674*10^-11 Nm^2 / kg^2

the attractive or repulsive force between two charged objects

F=k(q1*q2) / r^2

9*10^9 Nm^2 / C^2

the acceleration experienced by an object due to the force of gravity

g = GM / r^2

-9.81 m/s^2

the transfer of energy that occurs when a force is applied over a distance

W=Fd; W=Fdcosθ

the degree of an object's opposition to a modification in motion; a vector quantity,

p=mv

the change in momentum of an object over a given time period

J=Ft

the total momentum of a system of objects remains constant if no external forces act on the system

elastic, inelastic and perfectly inelastic

the total kinetic energy of the system is conserved

the total kinetic energy of the system is not conserved

the objects stick together and travel in the same direction

a type of periodic motion where the restoring force is directly proportional to the displacement from the equilibrium position and is directed towards it

the acceleration is directly proportional to the displacement and is always directed towards the equilibrium position

is constant and is the sum of kinetic and potential energy

PEe=1/2 kx^2

Since the block is accelerating and decelerating, there must be some force that is making it do so. This cause, the spring exerts a force on the b

The motion of an object moving in a circular path at a constant speed. The velocity is constantly changing due to the change in direction of its motion.
