Describe a collision in which all kinetic energy is lost, yet the total energy is conserved . ... Since they are not moving after the collision the kinetic energy (of motion) is transferred to mostly heat. The total energy is always conserved. There can be no motion after the collision.
Is it possible for an object to receive a larger impulse from a smaller force than from a large force?
6) Is it possible for a body to receive a larger impulse from a small force than from a large force? Answer: Yes. Impulse is force times time . A small force acting over a long time can easily provide more impulse (change in momentum) than a larger force which acts for a much shorter time.
Why can a batter hit a pitched baseball further than a ball tossed in the air by the batter?
Why can a batter hit a pitched baseball further than a ball tossed in the air by the batter? The batter hit changes the direction of the momentum (with little loss of velocity) and the batter swings at the ball adding more impulse to the ball . These motions combined allow for a home run.
What is momentum short answer?
Momentum is a physics term; it refers to the quantity of motion that an object has. ... If an object is in motion (on the move) then it has momentum. Momentum can be defined as “ mass in motion .” All objects have mass; so if an object is moving, then it has momentum – it has its mass in motion.
Is it possible to have an inelastic collision in which all the kinetic energy of the colliding objects is lost if so give an example if not why not?
Kinetic energy is rarely conserved . Only in perfectly elastic collisions. BUT total energy is always conserved in whatever form. In a perfectly inelastic collision (ie when the objects ‘stick together’ or coalesce, the MAXIMUM amount of KE is lost.
Is it easier to hit a homerun from a pitched ball than from one tossed in the air by the batter?
WHY can a batter hit a pitched baseball further than a ball tossed in the air by the batter? ... The bat changes the direction of the momentum (with little loss of velocity) and the batter swings at the ball adding more impulse to the ball. These motions combined allow for a home run.
How can a small force impact the same impulse as a large force?
How can a small force impart the same momentum to an object as a large force? Impulse is the product of force and time. A large force applied for a short period of time can produce the same momentum change as a small for applied for a long period of time.
Do objects stick together in an inelastic collision?
People sometimes think that objects must stick together in an inelastic collision. However, objects only stick together during a perfectly inelastic collision . Objects may also bounce off each other or explode apart, and the collision is still considered inelastic as long as kinetic energy is not conserved.
Is Ke conserved in an explosion?
Explosions occur when energy is transformed from one kind e.g. chemical potential energy to another e.g. heat energy or kinetic energy extremely quickly. So, like in inelastic collisions, total kinetic energy is not conserved in explosions .
What happens when two very heavy objects collide?
Newton’s third law of motion is naturally applied to collisions between two objects. In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction . Such forces often cause one object to speed up (gain momentum) and the other object to slow down (lose momentum).
What are the two types of momentum?
There are two kinds of momentum, linear and angular . A spinning object has angular momentum; an object traveling with a velocity has linear momentum.
What is momentum in real life?
Momentum in a simple way is a quantity of motion . ... If an object does not move then it has no momentum. However, in everyday life it has an importance but many people didn’t recognize it. Momentum is just about every activity that involves motion. It is an essential concept of physics.
What is momentum in physics for kids?
Momentum is a measurement of mass in motion. Any object that is moving has momentum. In physics, momentum of an object is equal to the mass times the velocity .
What is conserved when two objects collide in a closed system?
For all collisions in a closed system, momentum is conserved . In some collisions in a closed system, kinetic energy is conserved. When both momentum and kinetic energy are conserved, the collision is called an elastic collision. ... Much more common are inelastic collisions.
When two objects collide and stick together the collision is said to be inelastic?
Collisions in which the kinetic energy is not conserved, i.e. in which some ordered energy is converted into internal energy, are called inelastic collisions. If the two objects stick together after the collision and move with a common velocity v f , then the collision is said to be perfectly inelastic .
Is momentum conserved when two objects collide and stick together?
A collision in which the objects stick together is sometimes called “perfectly inelastic.” An inelastic one-dimensional two-object collision. Momentum is conserved , but internal kinetic energy is not conserved.
