TIPOS DE FORÇA NA FÍSICA: FORÇA PESO | Resumo de Física Enem. Prof. Márcio Rossetto

📚 Natural Sciences E-book: http://bit.ly/35OYaeg #weightforce #enemphysics #force Learn the definitions, applications, and calculations of the Weight Force with physics professor Márcio Rossetto, from the Free Enem Course channel. The Weight Force is nothing more than the result of the action exerted by the Earth on bodies when they are close to it. We are talking about a field force. And like any other force, its unit of measurement is Newton (N). Newton is equivalent to kg.m/s².

Today, we'll look at weight. 00:38 - Weight is a field force. Therefore, it doesn't require contact to exist. 1:45 - To calculate weight, simply multiply the object's mass by the gravity of its location. The direction is vertical. The direction is downward. 2:40 - Attention! Normal force is NOT a reaction to the weight. Check out our Newton's Laws lesson to remember this :) 3:08 - Mass should be in kg. 3:19 - Exercise 1. 5:09 - Exercise 2. 6:22 - Conclusion.
