4th quarter science

• law of acceleration - newton's second law of motion
• the law of acceleration - produced by a net force directly proportional to the magnitude of the net force
• acceleration - change in velocity with time
• vector quantities - has both magnitude and direction
• scalar quantities - magnitude only, no direction
• uniformly accelerated motion - changes by an equal amount in every time period
• velocity - how position changes in time
• gravity - grabs objects towards its center
• 9.8m/s2 - acceleration due to gravity
• trajectory - arc or curved like motion path
• parabola - arc or curved like shape taken by a projectile
• projectile - object given initial velocity
• range - horizontal distance covered by a projectile
• maximum height - maximum vertical distance reached by projectile
• momentum - means mass in motion
• p = mv - formula for momentum
• has mass and in motion - what to consider in defining momentum
• impulse - change in momentum
• I = trianglep - solutionfor impulse
• I=Ft=mv - solution for impulse and momentum
