A moving body comes to stop without an application of force. Comment.

Can KE of a system be increased or decreased without the application of external force?

A bus is moving with a speed of 18 kilometre per hour it comes to rest in 3 second on the application of brakes find the retardation​, assuming it to be uniform.

If two bodies are moving towards each other without any external forces and join, then centre of mass

A car of 1000 kg moving with a velocity of 30 m//s stops with uniform acceleration after covering a distance of 50 m on application of brakes. Find the force applied by the brakes on the car and also work done.

Why does a body stop after rolling down for some time ?

If the work done by a body on application of a constant force is directly proportional to the distance travelled by the body, express this in the form of an equation in two variables and draw the graph of the same by taking the constant force as 5 units. Also read from the graph the work done when the distance travelled by the body is :-2 units

If the work done by a body on application of a constant force is directly proportional to the distance travelled by the body, express this in the form of an equation in two variables and draw the graph of the same by taking the constant force as 6 units. Also read from the graph the work done when the distance travelled by the body is:- 0 unit

Can a body have momentum without energy?
