Why does fission release energy?
Fission releases energy because when a heavy atomic nucleus splits into smaller nuclei, the total mass of the products is less than the original mass, and this "missing" mass is converted into energy according to Einstein's famous equation, Emc2.
How is the mass defect used in fission power plants?
The mass defect in fission power plants is used to release energy by converting a small fraction of the mass of a heavy nucleus into energy during nuclear fission. This energy is then used to generate heat, which is converted into electricity through turbines and generators. The difference in mass before and after the fission reaction contributes to the energy released.
Which has the greater kinetic energy a light car or a heavy truck?
The heavy truck likely has greater kinetic energy because kinetic energy is directly proportional to an object's mass. Since the truck has more mass than the light car, it would usually have more kinetic energy when they are both moving at the same speed.
When work is done on an object does the object gain energy?
If you push a round heavy object up an incline it has gained energy based on the distance and the height of the incline, at rest at the bottom the potential engery was a factor of its mass, movement from point A at the bottom to point B at the top gave it energy that change from potential to kinetic when released at the top to roll back down.
What is Stan's mass if he does 162 J of lifting himself 0.1 m?
To find Stan's mass, we can use the formula for gravitational potential energy: PE = mgh. Given that Stan performed 162 J of work lifting himself 0.1 m against gravity, his mass can be calculated as m = PE / (gh) = 162 J / (9.8 m/s^2 * 0.1 m) = 16.53 kg.
Does lifting heavy weights help to gain body mass or gain weight?
Cause you get stronger and thatputs on weight
What is a repeating disturbance or vibration that transfers or moves energy from place to place without transporting mass.?

How do you increase the potential energy of a wagon without increasing its mass?
You can increase the potential energy of a wagon by lifting it to a higher elevation. This increases its gravitational potential energy without changing its mass.

Define laws of conservtion of mass?
The law of conservation of mass, or principle of mass conservation, states that for any system closed to all transfers of matter and energy (both of which have mass), the mass of the system must remain constant over time, as system mass cannot change quantity if it is not added or removed.
How is the mass defect used in fission power plants?
The mass defect in fission power plants is used to release energy by converting a small fraction of the mass of a heavy nucleus into energy during nuclear fission. This energy is then used to generate heat, which is converted into electricity through turbines and generators. The difference in mass before and after the fission reaction contributes to the energy released.
Why closed system is termed as control mass?
A closed system is termed as a control mass because it does not exchange mass with its surroundings. This means that no mass enters or leaves the system, and therefore the total mass within the system remains constant. This allows for the analysis of the system's energy changes and thermodynamic processes in isolation, making it a control mass for studying energy transfers and conservation.
Which has the greater kinetic energy a light car or a heavy truck?
The heavy truck likely has greater kinetic energy because kinetic energy is directly proportional to an object's mass. Since the truck has more mass than the light car, it would usually have more kinetic energy when they are both moving at the same speed.
What are the two ways that you can increase gravitational energy?
GPE can be increased by lifting a heavier object i.e. increasing mass, or by lifting the object higher i.e. increasing height. This is described by E=mgh. Where m and h are the variables explained previously.
What is potential energy and give and example?
Potential energy exists when a force acts upon an object that tends to restore it to a lower energy configuration. This force is often called a restoring force. For example, when a spring is stretched to the left, it exerts a force to the right so as to return to its original, unstretched position. Similarly, when a mass is lifted up, the force of gravity will act so as to bring it back down. The action of stretching the spring or lifting the mass requires energy to perform. The energy that went into lifting up the mass is stored in its position in the gravitational field, while similarly, the energy it took to stretch the spring is stored in the metal.
