How can a wheel and axle help us? In addition to reducing friction, a wheel and axle can also serve as a force multiplier, according to Science Quest from Wiley. If a wheel is attached to an axle, and a force is used to turn the wheel, the rotational force, or torque, on the axle […]

Do amps matter on a battery? If the power supply can supply more than 2.1Amps this doesn’t matter as the product will only take 2.1Amps. If the power supply can only supply 1 Amp in this case then either the product will fail to work/charge or charge slowly as it can’t get enough current (or […]

What is an example of the Stroop effect? The Stroop effect is a phenomenon that occurs when you must say the color of a word but not the name of the word. For example, blue might be printed in red and you must say the color rather than the word. What causes the Stroop effect? […]

What is the function of a diode? A diode is a semiconductor device that essentially acts as a one-way switch for current. It allows current to flow easily in one direction, but severely restricts current from flowing in the opposite direction. What is the two main function of a diode? Main functions The most common […]

What happens first in the life of a plant? Life Cycle. The plant starts life as a seed, which germinates and grows into a plant. The mature plant produces flowers, which are fertilised and produce seeds in a fruit or seedpod. The plant eventually dies, leaving seeds which germinate to produce new plants. What happens […]

Does the mass ever change? The mass of an object does not change with speed; it changes only if we cut off or add a piece to the object. Since mass doesn’t change, when the kinetic energy of an object changes, its speed must be changing. Special Relativity (one of Einstein’s 1905 theories) deals with […]
