Have you ever heard the phrase ‘what goes up must come down’? Well, it surely points towards gravity. In this video, students will get to learn about gravitational force and some of the mighty discoveries made about it. Gravitational force pulls objects towards each other. The planets orbiting the sun, the appearance of tides in our Earth’s oceans, and air circulation, are, to name a few, processes that operate due to this force. The law of universal gravitation, proposed by Sir Isaac Newton was a breakthrough in the field of science. Moreover, Sir Albert Einstein’s proposed the idea that gravity not only acts on non-zero masses, but also on light. An interesting fact is that black holes have the highest gravitational force in our universe. This happens because in a black hole, a lot of mass is concentrated in a small volume of space.
This video satisfies the 5-PS2-1 requirement of fifth-grade science proficiency.
Students who demonstrate understanding can: 5-PS2-1. Support an argument that the gravitational force exerted by Earth on objects is directed down.
