Impulse & Momentum
... A few weeks ago I did a lecture demonstration where I yanked a tablecloth out from under some dishes. Can you briefly explain why the dishes were not given much impulse by the tablecloth. Impulse is defined as force time the change in time. If the change in time is very small, the impulse is going t ...

Momentum and Collisions
... Therefore the law of conservation of momentum is stated: “as the total momentum of all objects interacting with one another remains constant regardless of the nature of the forces between the objects.” This law holds true if the objects collide or the objects push away from each other as in a person ...

An Investigation of a Model for Air Resistance
... Introduction: When an object falls near the Earth’s surface it experiences the force of gravity as well as a drag force due to air resistance. In first year physics, most students are told to “ignore” wind resistance. This lab is designed to show that a model equation may be tested. One of the simpl ...
