### Gravitation: Why does a stone fall towards the earth but the opposite is not observed?

##### Gravitation

Gravitation and a Falling Stone As said by this law of universal gravitation every object in this universe is attracting every other object towards it. This force of gravitational attraction between any two objects in the universe is inversely proportional to the square of the distance between the objects. This force is again directly proportional

### What will happen to a ball thrown vertically upwards?

##### Gravitation Motion

Motion of a ball thrown vertically upwards You must have seen someone throwing a ball vertically upwards or probably you have thrown it yourself. Yes, the ball goes up for a while and then stops and starts to come down and touches the ground with a bang if you can’t catch it. Let’s discuss the phases

### Pushing a car, Newton’s 3rd Law and Friction

##### Force Frictional force Motion

Pushing a car and Newton’s third law Hope you have seen people pushing their car when it’s not starting due to some issue. When someone is pushing a car or something like that, he first pushes the ground or floor backwards with his feet. Following the ‘3rd law of Newton’ the ground also exerts an equal

### Work done by a force

##### Work, Energy, Power

Work done by a Force In Physics Work is done by a force applied only if the object on which the force is applied makes a displacement. Without this displacement, work done is zero irrespective the force you have applied. Work done by a force depends on the 3 parameters, (a) the force applied (b)
