The net force is the vector sum of all the forces acting on the object....So that is...(20+10=30)N acting in the same direction.........
35 Newtons in the same direction as the aforementioned forces.
The net force on the object is 5 newtons toward the north.
The net force would be 5 N to the north. (10 - 5)
Ten newtons downward, by definition.
10N - 2N = 8N North
35N
Gravity is forcing an object to fall to the ground. Another force is friction from air pressure on the falling object.
Net force=ma=25N
If an object is in "free fall", it means that the only force acting on it is gravity.
Acceleration. A free-falling object falls at constant force, and thereby at constant acceleration.
Ten newtons downward, by definition.
motion of free falling object does not have friction, while motion of the cart has force of friction
It doesn't, since the conditions don't apply. The conditions for Newton's First Law are that there is no net force on an object - there must be no force on the object, or the vector sum of the forces must be zero.
It sure does! Look up Newton's law of universal gravitation. Basically it states that each object exerts the exact same amount of force upon the other. For example, your weight on Earth is exactly the same as Earth's weight on you. And if you are freely falling toward the Earth, then the Earth is freely falling toward you. You don't notice it, because the accelerations are inversely proportional to the masses, and the Earth has quite a bit more of that than you have.
no force act on it
The gravity acting on a rising object and that on a falling object are the same when these objects are at the same height. What is different is that a rising object is decelerating by the force of gravity and the falling object is accelerating.
Yes. The definition of "free fall" implies that gravity from Earth - or perhaps from different objects - is acting on the body.
Gravity is a force that accelerates the falling object towards the ground.
