- 1. • Change of position inreference to an assumed pointor center with respect to time;a shifting movement.
- 2. • a motion in a straight line, circleor circular arc, or helix (simplemotion of a clock pendulum).
- 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. • 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. • 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. • A freely falling object is an object that movesunder the influence of gravity only.Formula:v = v0 – gty = v0t – ½ gt2v2 = v02 - 2gy
- 7. - anything that changes or tends to change thestate of rest or motion in a body
- 8. Force (f) = mass (m) x acceleration (a)
- 9. 1. Gravitational Force2. Electromagnetic Force3. Nuclear Force4. Weak Force
- 10. • The force in a springor almost any otherobject isproportional to theamount ofstretch, twist, bendor otherdisplacement.
- 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. “The unbalanced force acting on an objectequals the object’s mass times itsacceleration.”Fn et = ma
- 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. 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. –is a conserved quantity.–Is mass times velocity.
- 16. –is the rate at which it moves or travels–distance travelled per unit of time
- 17. –the time rate of change of displacement–Is a vector quantity wherein we have toconsider both magnitude and directionVELOCITY = distancetime
- 18. –The time rate of change in velocity
