One-Dimensional Motion:
● Displacement:
● Symbol: s
● Defined as the change in position of an object
● Has both magnitude and direction
● Velocity:
● Symbol: v
● Defined as the rate of change of displacement
● Also has both magnitude and direction
● Acceleration:
● Symbol: a
● Defined as the rate of change of velocity
● Can be constant or variable
Linear Momentum and Conservation of Linear Momentum:
● Momentum:
● Symbol: p
● Defined as the product of mass and velocity of an
object
● Has a constant magnitude in the absence of a net
external force
● Conservation of Linear Momentum:
● The total linear momentum of a closed system
remains constant
● Applies to both elastic and inelastic collisions
Motion in a Plane: Components, Resultant
● Components:
● The x-component and y-component of motion can be
calculated separately
● The resultant is the vector sum of the components
● Resultant:
, ● Symbol: R
● Defined as the straight-line distance from the origin to
the end point of the motion
● Can be calculated using the Pythagorean theorem
Centripetal Force and Conservation of Momentum
● Centripetal Force:
● Symbol: Fc
● Acts perpendicular to the direction of motion
● Required for an object to move in a circular path
● Conservation of Momentum:
● The total linear momentum of a closed system
remains constant
● Applies to both elastic and inelastic collisions
Work, Energy, and Power: Kinetic and Potential Energy
● Work:
● Symbol: W
● Defined as the force applied multiplied by the distance
moved
● Can be positive, negative, or zero
● Energy:
● Kinetic Energy: energy of motion
● Potential Energy: energy of position
● Power:
● Symbol: P
● Defined as the rate of doing work
● Measured in watts (W)
