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
Slide3Determining 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
Slide4Force
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
Slide5Speed
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
Slide6Acceleration
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
Slide7Velocity
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.
Slide8Average 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
Slide9Net 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
