Physics

• Momentum


  Change in motion
• Impulse - change in momentum
• P = mv
• M = p/v
• V = p/m
• Elastic - 2 objects bounce off of each other
• Collision - when two or more objects come together and interact with one another
• Inelastic - 2 objects stick together
• Inelastic - KE changes
• Elastic - KE does not change
• d = vi + vf / 2 * t
• d = vi * t + 1/2 * a * t^2
• vf^2 = vi^2 + 2 * a * d
• vf = vi + a * t
• Horizontal motion is the x component
• Horizontal velocity is constant (Vx)
• Acceleration is 0 for Horizontal motion, ax = 0
• Horizontal distance is called Range
• Vertical motion is the y component
• vertical velocity is NOT constant (Vy)
• Vertical distance is called height
• The acceleration for vertical motion is equals to gravity (9.8m/s^2)
• m/s^2 = acceleration
• m = distance
• m/s = final velocity
• distance = speed * time
• speed = distance/time
• time = distance/speed
• vector quantity needs direction
• scalar does not need direction
• The answer to p=mv is kg.m/s
• The answer to I=ft is N.S
• the formula to impulse is I=ft
