Newtonian Laws of Motion 0.0 / 5 ? PhysicsMotionA2/A-levelOCR Created by: Lagini NavamCreated on: 02-03-14 18:35 Newton's 1st Law An object will remain at rest or will keep moving at constant velocity unless acted upon by an external force 1 of 7 Newton's 2nd Law The net force of an object is equal to its rate of change in momentum 2 of 7 Newton's 3rd Law If body A exerts a force on body B then body B will exert an equal and opposite force on body A 3 of 7 Momentum Mass x Velocity 4 of 7 Impulse Force x Time 5 of 7 Perfectly Elastic Collision Kinetic energy is conserved (momentum and total energy are always conserved) 6 of 7 Inelastic Collision Kinetic energy is not conserved- it is transferred into other forms off energy eg heat 7 of 7
