is a quantity that describes
when an event took place

Time

Unit of time?

s - Seconds
min - Minutes
hr - Hour

is the total length
traveled by a moving object.

Distance

Is Distance a scalar or vector quantity?

Scalar Quantity

Common Units of Distance?

cm - Centimeter
m - Meter

is the length and
direction of the line that connects
the initial and final position.

Vector quantity

Common Units of Displacement?

cm to the NEWS - Centimeter North, East, West, South
m to the NEWS - Meter North, East, West, South
km to the NEWS - Kilometer North, East, West, South

is the rate of change in
position.

Speed

Is Speed a scalar or vector quantity?

Scalar quantity

Common units of Speed?

m/s - meters per second
km/h - kilometers per hour
mph - miles per hour

is the rate of change in
position with respect to a
reference point.

Velocity

Is Velocity a scalar or vector quantity?

is the rate of change
in velocity.

Acceleration

is Acceleration a scalar or vector quantity?

Vector quantity

Common Unit for Acceleration?

m/s² - meters per second squared

• all parts of the body move the same distance in a given time

Translational

A type of Translational that moves along a straight line

RECTILINEAR MOTION

A type of Translational that moves along a curved path

CURVILINEAR MOTION

simplest kind of rotation, points on a rigid object move on circular paths around an axis of rotation.

Rotational motion

• The angle through which the object rotates

• a rigid body rotates about a fixed axis, the angular displacement is
  the angle swept out by a line

• Intersecting the axis of rotation perpendicularly

Angular Displacement

Unit of Angular Displacement?

Radian (Rad)

• The change in position of an object measured along a straight
  line

• measured in meters (m)

Linear Displacement

• An angle through which an object rotates around an axis

• Measured in radians (rad)

Angular Displacement

• Rate of change in position with time

• Vector quantity with direction

• Measured in meters per second

Linear Velocity

• Rate of change of angular position with time

• Vector quantity perpendicular to a plane of rotation

• Measured in radians per second

Angluar Velocity

• Rate of change of velocity with time

• Measured in meters per second squared

Linear Acceleration

• Rate of change of angular velocity with time

• Measured in radians per second squared

Angular Acceleration

• A product of mass and velocity. Describes an objects tendency to continue moving in a straight line

Linear Momentum

• A product of movement of inertia and angular velocity . Describes an objects tendency to continue rotating
