Answers 1. What is meant by collision theory? Collision theory states that chemical reactions occur when reactant particles collide with sufficient energy and in the correct orientation to overcome the bonds holding the reactant particles together. 2. What is activation energy? The minimum energy that particles need to collide with in order to ...

Reactants are substances that enter into a reaction, and products are substances produced by the reaction. The Collision Theory Gizmo allows you to experiment with several factors that affect the rate at which reactants are transformed into products in a chemical reaction.
Answer: D. In any collision, there are always four quantities which are the same for both objects involved in the collision. Each object experiences the same force (Newton's third law) for the same amount of time, leading to the same impulse, and subsequently the same momentum change.

A collision is when two objects impact each other over a short space of time. The momentum of each object can change, but the total momentum does not. We say the momentum is conserved (the total stays the same).

We can combine the equations for Newton’s 2nd Law and acceleration to express force as a change in momentum: Newton’s 2nd Law: F = ma. Acceleration: a = \dfrac {v-u} {t}. Combine them to get: F = \dfrac {m\left (v-u\right)} {\Delta t} This can be written as: \textcolor {00bfa8} {F = \dfrac {m \Delta v} {\Delta t}}
