A simple wheel and axle
Remove the cover from a pencil sharpener and bind a string tightly around the end of the shaft. Bind a weight of various kilograms to the end of the string and turn the handle. Note that the force required to turn the handle is much less than the force of gravity on the weight. Point out that the pencil sharpener is used as a wheel and axle in this demonstration.

On the way to school, Jamal realizes that he left his physics homework at house. His car was initially heading north at 24.0 m/s. It takes him 35.5 s to turn his car around and hea
A student calculates the acceleration due to gravity and determine it to be 9.72 m/s 2 . What is his percent error, if the accepted value is 9.81 m/s 2 ? Q. You estimate that th
Can you explain Ohms Law? Ans. If Temperature remains constant then current flow is directly proportional to applied Voltage. I ∝ V, I = V/R (resistance of the conductor)
