What else can I help you with?
Are matter and energy together are always conserved true or false?
True. According to the law of conservation of mass-energy, matter and energy can neither be created nor destroyed, only transferred or transformed from one form to another. So, in any isolated system, the total amount of matter and energy remains constant.
Energy is conserved when an object gains speed while falling?
Yes, energy is conserved in a falling object when it gains speed. The potential energy of the object due to its position is converted into kinetic energy as it accelerates, keeping the total energy constant.
What is true about conservation of energy?
The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another. This principle applies to all forms of energy, such as kinetic, potential, thermal, and chemical energy. Energy is always conserved in a closed system.
Why is kinetic energy conserved in elastic collisions?
In elastic collisions, kinetic energy is conserved because the total energy of the system remains constant. This means that the initial kinetic energy of the objects involved in the collision is equal to the final kinetic energy after the collision. This conservation of energy principle holds true as long as no external forces, such as friction or air resistance, are present to dissipate the energy.
How did the elastic collision effect the total momentum and total kinetik energy in the system?
In an elastic collision, the total momentum of the system is conserved, meaning the total momentum before the collision is equal to the total momentum after the collision. However, the total kinetic energy in the system is also conserved in an elastic collision, which means it remains the same before and after the collision.

What is true about the total energy of a ball as it rolls down a hillside?
It is conserved. The potential energy of the ball sitting at the top of the hill is converted into kinetic energy of the rolling ball.

Is it true or false that generators create electrical energy from nothing?
false; you cannot get energy from nothing, it is conserved

However, the total kinetic energy in the system is also conserved in an elastic collision, which means it remains the same before and after the collision.
In a nuclear reaction mass must be lost to produce energy. true or false?
False. Both mass and energy are conserved.
Is it true that the law of conservation of energy stated that momentum is conserved in a collision?
Is it true that the law of conservation of engery states that momentum is in a collision
Is it true or false that because energy is conserved as the amount of one type of energy increases the amount of another type of energy must decrease?
True, according to the principle of conservation of energy, in an isolated system, energy can neither be created nor destroyed, only transferred or converted from one form to another. Therefore, if the amount of one type of energy increases, another type of energy in the system must decrease to maintain the total energy constant.
For the chemical reaction H2 CO2--H20 Co the energy contained in the reactants is 352 kj and the energy contained in the products is 394 kj assuming 1 mol of each substance is present is this true?
No, this is not true. The energy contained in the reactants is 352 kJ, and the energy contained in the products is 394 kJ, suggesting that energy was released during the reaction. However, energy should be conserved in a chemical reaction, so the total energy in the products should be equal to the total energy in the reactants.
In what situations does the law of conservation of energy not apply?
In general Conservation of Energy does not hold internal to a system, it only holds at the boundary of the system. This is where the limits of the system are. Internal to the system energy is not conserved. The situations where the Conservation does not apply is where the force is not zero or the first derivative of energy is not zero.
