Why is the centroid called the center of mass?
centroid is called centre of mass because it works on mid point theorm which is a average of total mass concentrated on centre of triangle.

The centroid is called the center of mass because it represents the point where the entire mass of an object can be considered to be concentrated. This means that if the object were suspended from this point, it would be in perfect balance. The centroid is calculated by finding the average position of all the individual mass elements of the object.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- What are some examples of impulse?
- A ball with a mass of #5# #kg# moving at #2# #ms^-1# hits a still ball with a mass of #6# #kg#. If the first ball stops moving, how fast is the second ball moving?
- A ball with a mass of #4 kg# moving at #9 m/s# hits a still ball with a mass of #5 kg#. If the first ball stops moving, how fast is the second ball moving? How much heat energy was lost in the collision?
- Does the coefficient of restitution change?
- A ball with a mass of #2 kg# moving at #8 m/s# hits a still ball with a mass of #9 kg#. If the first ball stops moving, how fast is the second ball moving? How much kinetic energy was lost as heat in the collision?
