Yoyo is a toy that everyone has played at some point in their lives. Yoyo is more than twenty five thousand years old. It is the second oldest toy‚ after dolls. The yoyo was first documented to be invented in Greece with wood‚ metal and terra cotta.2 .The disks were decorated with the pictures of their gods. The yoyo moved to the Orient around 1800. The yoyo was used as a weapon in Philippines. Their version was large with sharp edges and spikes attached to a twenty foot long rope for flinging at

A block if wood of mass 6.0 kg slides along a skating rink at 12.5 m/s [W]. The block slides onto a rough section of ice that exerts a 30 N force of friction on the block of wood. Calculate: a. the acceleration of the block of wood. [5.0 m/s2 [E]] b. the time it takes the block of wood to stop [2.5 m/s] c. how far the block slides after friction begins to act on it. [15.6 m] 5. A force of 36 N gives a mass m1 an acceleration of 4.0 m/s2. The same force gives a mass m2 an acceleration of 12 m/s2

Purpose: Predict how forces can change motion. Provide reasoning and evidence to explain motion changing or not. Answer in Complete Sentences. Open the Forces and Motion Basics simulation and play with the Friction screen for a few minutes. Set your value like the picture below. Imagine that your friend‚ Sam is trying to move a box. Using what you learned by exploring‚ try drawing arrows to predict what might happen in the pictures below. (Try this part without using the simulation.) Sam

like all sports can be explained by science. People that play basketball like me also uses science‚ by gravity‚ force‚ friction‚ and momentum. Players use force to push the ball toward the basket. The player fights gravity to take a jump shot to get to points for his team. On the court the player uses friction to begin moving along the floor. Basketball sneakers provide friction on the

Results If ski wax can be applied by rubbing‚ pasting‚ spraying‚ or melting then the melt on wax should reduce friction the best because it coats the skis more evenly and creates a thicker protective barrier to the bases of the skis. Consequently‚ this hypothesis was correct because the data captured displayed that the hot wax reduces friction the best‚ see appendix seven‚ eight‚ and nine. Hot melt on wax had the fastest time when the ice disc was slid down the ski and had the highest velocity. It

30-11.30am Conducted In : Fluid Mechanics Lab Abstract The main aim of this experiment was to show how the friction factor varies with Reynolds number by manipulating the flow rate of the fluid in a pipe. The main principle used in the experiment was the Bernoulli’s equation‚ taking major head losses into account. These major head losses were normally due to wall friction in the pipe and viscous forces between layers in a fluid. Generally the results obtain from the experiment do agree
