Question

1)why do all objects have a tendency to fall towards the earth when thrown up ?
2)difference between contact and non contact forces. support your answer with suitable examples.
3)how would the absence of friction change the world around us ?

please do this three questions .
I need urgently.

Answer 1

#1 when thrown object have a speed lesser than 11 to 11.6 km/s then it fall down cuz we need 11 to 11.6 km/s speed to escape the gravity of the earth. #2 when the applied force happens by touching something then it is contact force and when we do not touch something like gravitational or electrostatic force then it is non contact force. #3 without friction everything will slip from one place to other that can cause dangerous accidents. Are the answers right?
