Unit 4- Newton's Laws And Momentum Flashcards
Newton’s Second Law
Rate of change of momentum of a body is proportional to the net force acting on it and takes place in the direction of that force
Newton’s Third Law
When one body exerts a force on another the other body exerts an equal and opposite force on the first body
Linear momentum
Mass x Velocity
Principle of conservation of linear momentum
Total momentum is conserved for a closed system
Elastic Collision
Collision in which kinetic energy is conserved
Inelastic collision
Collision in which there is some loss of kinetic energy during the collision
Impulse of a force
Force x time for which the force acts
Newton’s First Law
A body will remain at rest or continue to move with constant velocity unless acted upon by a force
