Which form of energy causes a ball to hit the other balls on a pool table?
kinetic energy
What is it called when one form of energy is turned into another form of energy?
Energy transformation, also known as energy conversion, is the process of changing energy from one form to another. In addition to being converted, according to the law of conservation of energy, energy is transferable to a different location or object, but it cannot be created or destroyed.
Is mass conserved in an explosion?
Since total system momentum is conserved in an explosion occurring in an isolated system, momentum principles can be used to make predictions about the resulting velocity of an object….Solving Explosion Momentum Problems.
| Momentum Before Explosion | Momentum After Explosion | |
|---|---|---|
| Total | 0 | 0 |
Why does kinetic energy increase with an explosion?
However, the kinetic energy of each particle are equal since K.E. depends on speed, not velocity. (The velocities of the fragments have increased and so is the kinetic energy of the entire system (chemical energy → kinetic energy in the explosion) but the net momentum does not change.
When a moving object collides with an object at rest?
Both objects cannot be at rest. It is possible for one of the objects to be at rest after the collision. For example, if the masses of the two objects are equal, then after a head-on elastic collision the object initially at rest is moving and the object initially moving is at rest.
When an object strikes a stationary object of equal mass What is it called?
Total momentum is always conserved between any two objects involved in a collision. When a moving object collides with a stationary object of identical mass, the stationary object encounters the greater collision force.
Why do objects stick together?
An inelastic collision is one in which objects stick together after impact, and kinetic energy is not conserved. This lack of conservation means that the forces between colliding objects may convert kinetic energy to other forms of energy, such as potential energy or thermal energy.
Is the most important factor in determining how hard a vehicle will hit an object?
outside edges of the tire tread. When a moving object hits something, what is the most important factor in determining how hard it hits? increase.
