... After you pick up a spare, your bowling ball rolls without slipping back toward the ball rack with a linear speed of 2.85 m/s. To reach the rack, the ball rolls up a ramp that rises through a vertical distance of 0.53 m. (a) What is the linear speed of the ball when it reaches the top of the ramp? ...

Dimensions, Quantities and Units
... Work and energy are interchangeable quantities; work may be thought of as energy in transition. Thus, for example, in an internal combustion engine chemical energy in the fuel is changed into thermal energy which in turn produces expansion in a gas and then motion, first of a piston within a cylinde ...

potential energy
... A force is conservative if the kinetic energy of a particle returns to its initial value after a round trip (during the trip the Ek may vary). A force is nonconservative if the kinetic energy of the particle changes after the round trip (Assume only one force does work on the object). Gravitational ...

... The motion of a particle is governed by Newton’s second law, relating the unbalanced forces on a particle to its acceleration. If more than one force acts on the particle, the equation of motion can be written F = FR = ma where FR is the resultant force, which is a vector summation of all the force ...

Episode 214 - Teaching Advanced Physics
... We say that work is done by a force when the object concerned moves in the direction of the force, and the force thereby transfers energy from one object to another. You can be a typical physics teacher and use a board rubber to illustrate your point about energy gain. Alternatively, use some other ...

Hooke`s Law Problems
... 1. The force applied to a dynamics cart is measured with a stretched spring. What is the acceleration of a 2.0 kg cart on a flat, frictionless surface if pulled by a spring, of force constant 40 N/m, stretched by a constant amount of 8.0 cm? (1.6 m/s2) 2. What is the force constant of a Hooke's Law ...
