Slide1

Motion

Slide2

Motion

Motion is

the

process of moving or changing places or positionAnything you do while moving is motion.Fact: Speed is a major type of Motion

Slide3

Determining motion

In order to determine motion you must know direction and speed

To describe motion accurately and completely, a

Frame of Refrence* is necessaryYou can’t determine motion without a type of forceThe object’s motion doesn’t change if there is no force acted upon it* A system of objects that are not moving with respect to one another

Slide4

Force

Force*

is a major part in motion. Without force motion wouldn’t exist.

Force can speed you up or slow you downExamples of force: Wind Gravitational ForceElectrical ForceNormal Force* Strength

or energy as an attribute of physical action or movementFact: Electric force and magnetic force are the only forces that can both attract and repel

Slide5

Speed

Speed

* falls in multiple categories/subsections such as:

Acceleration VelocityAverage SpeedInstantaneous Speed* The ratio of the distances an object moves to the amount of time the object moves

Slide6

Acceleration

Constant Acceleration

Non-Constant Acceleration

Acceleration is equal to net force/mass

Acceleration is (A=

Vf

-Vi/T) the rate at which velocity

changes

Describes the situation in which the speed of an object is increasing, but isn’t always the result of changes in speed

Slide7

Velocity

The speed and direction in which an object is moving

Sometimes the motion of an object involves more than one velocity.

The change in velocity can be the result of a change in speed, a change in direction or bothAcceleration and Velocity are both vector quantities The velocity of an object moving in a straight line changes at a constant rate.

Slide8

Average and instantaneous speed

Average

The total

distance* travelledComputed for the entire duration of a trip, and instantaneous speed is measured at a particular instantInstantaneous

The rate at which an object is moving at a given timeExample is the speedometer*Distance- the length of the path between two points*Displacement- the direction from the starting point and the length of a straight line from the starting point to the ending point

Slide9

Net force & momentum

Net Force

Net

force is the overall force acting on an objectIf an object hits another object they produce the same net forceMomentumthe quantity of motion of a moving body, measured as a product of its mass and

velocityAn object has a large momentum if the product of its mass and velocity is largeThe loss of momentum in an object becomes a gaining in momentum in another object
