Is jumping a normal force? When we jump, the chemical energy in our muscles get converted to kinetic energy that exerts a force on the ground (that using Newton’s 3rd law), will trigger a reaction that will ‘push’ us up- and thus a jump. This resultant normal force = Mass x Distance of jump. Is […]

What is the difference between tables charts and graphs?
What is the difference between tables charts and graphs? Same, but Different Charts present information in the form of graphs, diagrams or tables. Graphs show the mathematical relationship between sets of data. Graphs are one type of chart, but not the only type of chart; in other words, all graphs are charts, but not all […]
Does specific heat depend on temperature?
Does specific heat depend on temperature? Therefore specific heat does not depend on temperature. What are the three factors affect the heat transfer that is necessary to change an object’s temperature? Experiments show that the transferred heat depends on three factors—the change in temperature, the mass of the system, and the substance and phase of […]

Is fracking good or bad?
Is fracking good or bad? In the U.S. alone, around 13 million metric tons of methane is released annually from natural gas wells alone. Fracking well sites are the source of a number of other air pollutants, which are less common than methane, but arguably more harmful to local populations. Where is fracking banned? Four […]

Why diesel engines are called CI engines?
Why diesel engines are called CI engines? Diesel engines are sometimes called compression-ignition engines because initiation of combustion relies on air heated by compression rather than on an electric spark. In a diesel engine, fuel is introduced as the piston approaches the top dead centre of its stroke. What is the difference between SI & […]
What are the disadvantages of using aluminum wire?
What are the disadvantages of using aluminum wire? The disadvantage of aluminum wiring is that it must be installed correctly to avoid the risk of house fires. When a current runs through aluminum wiring it causes the metal to expand. This creates a cycle of expanding and contracting called “cold creep.” In time, this can […]
