... A moving object has a property that is called momentum (moh-MEHN-tuhm). Momentum is a measure of mass in motion; the momentum of an object is the product of its mass and its velocity. Momentum is similar to inertia. To calculate an object’s momentum, you can use the following formula: momentum = mas ...

... When you strike a wall, does it hurt your hand? You might say the wall struck you. Newton would say the force you applied to the wall was the same as that which the wall applied to you. The wall is bigger and more massive, therefore has more inertia and was not harmed as much as you. If you push on ...

... In the collision of bullet and block, tension in string and weight are external forces but the net external force is zero. Therefore, momentum is conserved. Because the bullet is stopped in the block by friction, energy is not conserved in collision. But, after the collision, only gravity (a conserv ...
