### Motion

1. 1. • Change of position inreference to an assumed pointor center with respect to time;a shifting movement.
2. 2. • a motion in a straight line, circleor circular arc, or helix (simplemotion of a clock pendulum).
3. 3. investigates translational motion of objectsand deals with effects that forces have onmotionm is mass of objectis velocity vectoris linear accelerationvectoris linear momentumvectoris force vector
4. 4. • Uniform or constant acceleration is a type of motionwhich velocity of an object changes in equal amountin every equal time.• Formulas used in UAM:Vf = Vi + atVf² = Vi²= 2ada = Vi + at² or (Vi + Vf) t2
5. 5. • A formula used to model the vertical motion ofan object that is dropped, thrown straight up, orthrown straight down.Formula: y = ½ at² + v0t + y0y = heightt = timea = acceleration due togravityv0 = initial velocityY0 = initial height
6. 6. • A freely falling object is an object that movesunder the influence of gravity only.Formula:v = v0 – gty = v0t – ½ gt2v2 = v02 - 2gy
7. 7. - anything that changes or tends to change thestate of rest or motion in a body
8. 8. Force (f) = mass (m) x acceleration (a)
9. 9. 1. Gravitational Force2. Electromagnetic Force3. Nuclear Force4. Weak Force
10. 10. • The force in a springor almost any otherobject isproportional to theamount ofstretch, twist, bendor otherdisplacement.
11. 11. D. Newton’s Laws of Motion– This law refers to the natural tendency of anobject to resist being moved, which is calledinertia. Thus mass, is a measure of inertia.Fnet = 0 => a = 0 or v= const.
12. 12. “The unbalanced force acting on an objectequals the object’s mass times itsacceleration.”Fn et = ma
13. 13. “For every action of force upon an object, that objectin return will exert an equal and opposite force uponthe other object.”It is commonly stated as:“for every action there is an equal or oppositereaction”F12 = -F21
14. 14. E. Impulse and Momentum–Impulse is defined as the integral of aforce acting on an object, with respectto time.–Impulse changes the momentum of anobject.
15. 15. –is a conserved quantity.–Is mass times velocity.
16. 16. –is the rate at which it moves or travels–distance travelled per unit of time
17. 17. –the time rate of change of displacement–Is a vector quantity wherein we have toconsider both magnitude and directionVELOCITY = distancetime
18. 18. –The time rate of change in velocity
