Finally Newton's three laws of motion

appear constantly in our everyday lives.

These are just a few of many.

Thank you for watching.

And this concludes our

presentation! Laws of Motion in Cheerleading Newton's First Law of Motion First Law: If an object experiences

no net force, then its velocity

is constant: the object is either

at rest (if its velocity is zero), or it

moves in a straight line with constant

speed (if its velocity is nonzero). Newton's Second Law of Motion Second Law: The rate of change of

momentum is proportional to the

imposed force and goes in the

direction of the force. Newton's Third Law of Motion Third law: When a first

body exerts a force on a

second body, the second

body simultaneously

exerts a force on the

first body. This means

that both are equal

in magnitude and

opposite in direction. Analyze how Force affects Motion When your hands apply force against

the floor, the floor has force in the

opposite direction. When your legs

build momentum from your arms

swinging and you jumping it causes

your body to force itself over.

So it includes both one and

two dimensional forces. Speed, Velocity, and Acceleration. Formulas for Speed and Acceleration Speed = Distance/Time

Example: 420 mi./6hr. = 70 mi/hr *Speed-a scalar quantity that refers to "how fast an object is moving."

*Velocity-a vector quantity that refers to "the rate at which an object changes its position."

*Acceleration- The rate of change of velocity per unit of time. Acceleration- This is the rate of change of velocity.

Acceleration = change of velocity ÷ time

All unit must be in SI units

Example:

40 km/hr = 11.11 m/s

80km/hr = 22.22 m/s

Acceleration = 11.11÷ 2

Acceleration = 5.556 m/s² in the original direction. Explain how Motion is relative to a Reference Point A reference point shows the relation of an object and a moving/non-moving object.

Example: If you were in a plane flying around a building, it would appear that the building is moving instead of you inside the plane.
