What is wave interference and what two types are there?
What is wave interference and what two types are there? There are two types of interference: constructive and destructive. Constructive interference occurs when the wave amplitudes reinforce each other, building a wave of even greater amplitude. Destructive interference occurs when the wave amplitudes oppose each other, resulting in waves of reduced amplitude. What are sources […]
How does friction affect total mechanical energy?
How does friction affect total mechanical energy? Mechanical energy is reduced due to friction and converted to heat. This is the reason why there is an increase in temperature in objects that move against each other. The role of friction in a closed system is to convert a part of the total energy to heat. […]
How do I know if my photo tube is bad?
What happens if one of the cars collided with more force than the other one?
What happens if one of the cars collided with more force than the other one? Forces between two colliding objects It doesn’t matter if one car is heavier (more massive) than the other. The push force from one car will equal the push force from the other. What happens to the energy when two objects […]
What motion is illustrated by a ball thrown horizontally?
What motion is illustrated by a ball thrown horizontally? Objects experiencing projectile motion have a constant velocity in the horizontal direction, and a constantly changing velocity in the vertical direction. The trajectory resulting from this combination always has the shape of a parabola. What are the standard assumptions we make for horizontally launched projectiles? Assumptions […]

What is a disadvantage of using nuclear power?
What is a disadvantage of using nuclear power? Disadvantages of Nuclear Power The further implementations of nuclear power are limited because although nuclear energy does not produce CO2 the way fossil fuels do, there is still a toxic byproduct produced from uranium-fueled nuclear cycles: radioactive fission waste. What is the cheapest form of electricity? solar […]
What happens if you remove one bulb in a series circuit?
What happens if you remove one bulb in a series circuit? In a series circuit, every device must function for the circuit to be complete. One bulb burning out in a series circuit breaks the circuit. In parallel circuits, each light has its own circuit, so all but one light could be burned out, and […]
