momentum/ physics

• momentum = mass x velocity

  
• conservation of momentum - total momentum before an event is equal to the total momentum after the event.
• impulse = change in momentum / time
• force = impulse / time
• Newton's first law states that if there are no forces acting on an object, it will continue at constant speed or remain stationary.
• newton's first law states that if there are no forces acting on an object, it will continue at constant speed or remain stationary.
• Newton's second law states that force equals mass times acceleration (F=ma).
• newtons second law states that force equals mass times acceleration (F=ma)
• energy transfer = energy stored + energy lost
• Newton's third law states that every action has an equal and opposite reaction.
• newtons third law states that every action has an equal and opposite reaction.
• momentum is defined as the product of mass and velocity (p=mv)
• momentum is defined as the product of mass and velocity (p=mv) and has units of kgm/s.
