Momentum and Impulse
... If the force exerted on an object is NOT a constant force, finding the impulse/change in momentum is a little more difficult. As the saying goes, “If the forces varies… You must integrate!” ...

Circular Motion and Gravitation
... The situation is worse if the wheels lock--stop rotating--when the brakes are applied too hard. As long as the tires are rolling, the bottom of the tire is at rest against the road at each instant, so static friction exists. BUT, if the wheels lock, the tires slide and the friction force, which is ...

... Chapter 7 is about the COLLISION of two masses. Both masses are needed to understand their interaction. Newton's 3rd Law plays a very important part. Collisions involve two new concepts: Impulse and Momentum. Impulse concept leads to the Momentum definition. Also applied to two (or more) masses blow ...

This doesn’t mean no forces act on the object, it means that the forces act equally from opposite directions to cancel each other. So an object with no acceleration can either be mo ...
