Why Is Momentum Not Conserved? Momentum is not conserved if there is friction, gravity, or net force (net force just means the total amount of force). What it means is that if you act on an object, its momentum will change. This should be obvious, since you are adding to or taking away from the

When A Cannon Is Fired Why Do The Cannonball And Cannon Have Very Different Accelerations? Newton’s third law states that for every action there must be an equal and opposite reaction, so the forces on the cannon and cannonball are equal in magnitude (but not direction). and the mass of the cannon is larger than
When A Cannonball Is Fired The Momentum Of The System? Conservation of momentum explains why a gun or cannon recoils backwards when it is fired. When a cannon is fired, the cannon ball gains forward momentum and the cannon gains backward momentum. Before the cannon is fired (the ‘event’) the total momentum is zero. This
