The equation for momentum
Momentum = mass x velocity
Whats the conservation of momentum
Momentum of two bodies before collision is equal to the momentum of the two bodies after the collision
Newtons second law … Equation with force , momentum and time
Tsken
Force = change in momentum/ time taken
Whats the equation for work , force and distance
Work = force x distance
Equation for power in terms of energy transferred qnd time
Power = energy transferred/ time
