Forces and the Laws of Motion

Forces and the Laws of Motion. Changes in Motion. Force is a push or a pull exerted on an object. Force causes a change in velocity. A force acting on a mass causes an acceleration change in velocity. If 1 kg of mass is accelerated by 1 m/s 2 then 1 Newton (N) of force is needed.

Warm Up 7 10.27.11

Warm Up 7 10.27.11. Why should you choose an axe instead of a steel baseball bat to cut down a tree? (hint: Pressure=Force/Area). Applying Force - Pressure. The amount of force per unit of area is called pressure Pressure = force/area of application P=F/A

FRICTION

FRICTION. FRICTION - the force that present whenever two surfaces are in contact and always acts opposite to the direction of motion. Depends on : Type of materials in contact Surfaces of materials. Does NOT depend on: Surface area in contact Speed. F f = ? F n.

Friction

Friction. Friction - the force needed to drag one object across another. (at a constant velocity). Depends on: How hard the surfaces are held together (demo) What type of surface it is (I.e. rough, smooth). Not supposed to depend on: Surface area (pressure) Speed (low speeds) (demo).
