When the bat hits the ball, it exerts some force on the ball. Just think about a home run hitter hitting a stationary ball. How far do you think it will go? Will it go more than 400 ft.? Probably not. While the kinetic energy transferred from the bat to the ball accounts for some energy of the ball, it does not account for all. Where is the mysterious energy coming from?
The answer is conservation of momentum.
I just said momentum is conserved but how do I know that? I know that because of Newton's 2nd law: F=ma (Force equals mass times acceleration)
Conservation of momentum means that the harder you throw you, the harder the ball will bounce back at you. That is the reason it is easier to hit a home run on a fast ball than a curveball.
Conservation of momentum also means that the bat can transfer some of its momentum to the ball. This is why it is better to use a heavier bat if you swing just as fast. The momentum is the product of the mass and velocity, so to make it easier to understand; a heavier bat swung at the same speed as a lighter bat will have more momentum.

In psychology and usually in recruitment and processes of interviewing candidates for a job, the contrast error is a type of bias that occurs when the evaluation we make of a person is influenced by the impression that the previous persons made on us. In other words, the previous candidates and the impression they made on us set a benchmark that we will use to evaluate the other candidates and therefore, we'll be comparing the latter with the first ones.
In this example, Benny needs to assess Amanda's performance and he rates her as a good performer. However, then Benny thinks about an exceptional employee, Christina, and decides than compared with her, Amanda is just average. We can see that <u>the impression Christina is making on Benny is affecting the evaluation he is making of Amanda's performance since Amanda is setting a higher benchmark (since she is exceptional) that Benny is using to compare Amanda. </u>Therefore, Benny's rating is a contrast error.
In interview or performance appraisal process, error caused by the effect of previously interviewed or appraised applicants on the interviewer. It results in a conscious or subconscious comparison of one applicant with another, and tends to exaggerate the differences between the two.
