Weight is a measure of gravitational pull. So, the closer objects are to each other, the stronger their gravitational pull is. Earths gravity is what keeps you on the ground and what makes things fall. Albert Einstein discovered this principle. Albert Einstein described gravity as a curve in space that wraps around an objectsuch as a star or a planet. because the weight of an object is constant as long as the object remains on Earth. It holds down our atmosphere and the air we need to breathe. Question 3. answer choices . it is known as electrostatic attractive force.

Likewise, the forces of physics are at play in every moment of our lives from sticking a magnet on a fridge door to throwing a ball into a basketball hoop. Note also, that the net force responsible for pulling the cart to a stop is the force of friction. Why do you land on the ground when you jump up instead of floating off into space? And if you were on a planet with less mass than Earth, you would weigh less than you do here. It wasn't until other scientists repeated the experiment that they arrived at the modern value for \(G\). However, the forces are quite small, and it takes a great deal of mass to exert an easily detectable force. . Create flashcards in notes completely automatically. In simple words, it can be said that the object is moved away from the surface of applied force. Magnetism is a type of force.
