When 2 objects of the same mass traveling at the same speed collide is the energy canceled out?
The answer depends on the material of the objects. In physics, one useful concept is the concept of a perfect elastic collision, which is an idealization of the real world. An elastic collision is a collision where no deformation of objects is taking place, and thus the kinetic energy of the moving objects is preserved as no kinetic energy is transformed to heat or work during an elastic collision. In short, for elastic collisions, kinetic energy is preserved and not canceled out. In reality, there will always be some (or a lot) loss of kinetic energy to heat or work done in deforming objects, think of a car crash where there is a lot of kinetic energy spent in deformation of the cars (modern cars are designed to absorb a maximum amount of kinetic energy to be converted into deformation of objects in order to save lives), but in practical life there are many situations where the fraction of kinetic energy lost to heat or work during a collision may be neglected as it is very small. A good demonstration in real world is colliding billiard balls, or the stones used in the sport of curling, these kind of collisions may for practical purposes be considered elastic. The sum of kinetic energy and the sum of momentum for the moving objects are the same before and after the collision. This means, if 2 equal objects of same mass and same speed but opposite direction of movement collide head on in an elastic collision, their direction of movement will be reversed and their speed will be the same as before collision. Think of two equal billiard balls travelling at same but opposite speed colliding head on. When a moving object hits a moving object at an angle, or at rest or travelling at different speed or is of different mass, that is a different story, but the same rules of physics apply of course, the speed and directions of movement of the objects after any elastic collision may be easily calculated using Newton's laws.
What else can I help you with?
When two objects collide and completely stick together the collision is said to be inelastic True Or False?
True. In an inelastic collision, objects collide and stick together, resulting in a loss of kinetic energy.
When 2 objects collide what do they exchange?
When two objects collide, they can exchange energy and momentum. This exchange can result in changes in the objects' motion and speed. Additionally, they can exchange forces and potentially deform or damage each other depending on the nature of the collision.
What transfers heat energy between particles as they collide within a substance or between two objects in contact?
You seem to have answered your own question-it is the collisions that transfer energy
How does thermal energy transfer from hot objects to cold objects?
Thermal energy transfers from hot objects to cold objects through a process called conduction. This occurs when the particles in the hot object collide with the particles in the cold object, transferring energy and causing the cold object to heat up.
What is engery in motion?
Energy in motion refers to kinetic energy, which is the energy possessed by an object due to its motion. This energy is directly proportional to an object's mass and the square of its velocity. Kinetic energy is responsible for the ability of objects to perform work or transfer energy to other objects when they collide.
When objects kinetic energy can be transferred.?
When objects collide or touch, kinetic (mechanical) energy can be transferred.

Why do things bounce back when they collide?
When two objects collide, they bounce back. This is because if the two objects' momentum is the same, they would hit each other at the same force, but one object is probably heavier than the other, so the lighter object would fly back, while the heavier object's momentum would decrease. So both objects would bounce back no matter what.
How is heat transferred when objects touch?
When objects touch each other, heat is transferred through a process called conduction. In this process, heat energy moves from the hotter object to the cooler one as the particles of the two objects collide and transfer energy between them. The rate of heat transfer depends on the thermal conductivity of the materials and the temperature difference between the objects.
What happens when rocks in space collide?
When rocks in space collide, they can shatter into smaller pieces, merge together to form larger objects, or create debris fields. The impact can release a significant amount of energy, causing further fragmentation and altering the trajectories of the objects involved.
Can energy transfer happen between two objects when each object has the exact same energy?
When each object has the same energy, energy transfer can still occur between objects. The object with the greatest mass or traveling speed will transfer the energy.
How does gravity cause massive collisions?
Gravity causes massive collisions by attracting objects with mass towards each other. When two massive objects are traveling towards each other due to gravitational pull, they can collide with great force, releasing a huge amount of energy. This process is seen in celestial bodies such as galaxies, stars, and planets.
