Does collide mean crash?
If two or more moving people or objects collide, they crash into one another. If a moving person or object collides with a person or object that is not moving, they crash into them.
Why do things collide?
Collisions involve forces (there is a change in velocity). The magnitude of the velocity difference just before impact is called the closing speed. All collisions conserve momentum. What distinguishes different types of collisions is whether they also conserve kinetic energy.
What is collide in biology?
collision theory, theory used to predict the rates of chemical reactions, particularly for gases. The collision theory is based on the assumption that for a reaction to occur it is necessary for the reacting species (atoms or molecules) to come together or collide with one another.
