There may be none, or there may be a whole bunch of forces on a body at rest.
There's no way to tell.
The only thing you know for sure is that if the body is at rest ... or even if it's moving
but its speed and direction of motion aren't changing ... then all the forces on it, if any,
add up to zero.
When the net force acting on the body is zero. The body will remain in equilibrium until an external force is applied to the body.
It can be a force or the absence of a force. A body at rest remains at rest unless it is acted on by a force. But, a body in motion will continue to move at a constant velocity (change its position) unless it is acted by a force.
a force lil' G !!
Starting from rest, a 2 kg body acquires a speed of 8 m/s in 2 seconds. The net force acting on the body is
Rest. At rest denotes a constant velocity including velocity of zero. Newton's Law says that a body will change its velocity ,accelerate or decelerate, only when an external force is applied. No force, no acceleration, no change in velocity. At rest itself denotes no force.
When the net force acting on the body is zero. The body will remain in equilibrium until an external force is applied to the body.
An unbalanced force.
The force accelerates the body, a=F/m.
It can be a force or the absence of a force. A body at rest remains at rest unless it is acted on by a force. But, a body in motion will continue to move at a constant velocity (change its position) unless it is acted by a force.
a force lil' G !!
Gravity, pressure.
a force that works between a body at rest & the plane upon which it is resting.
When force is applied on a body originally at rest, the body begins to move. For example, a car originally at rest when pushed, begins to move. A grass roller when pulled begins to move. A ball lying on the ground moves when it is kicked.
The normal force causes a body to move from its rest position and covers a distance.
Starting from rest, a 2 kg body acquires a speed of 8 m/s in 2 seconds. The net force acting on the body is
a body at rest will stay at rest unless acted on by an unbalanced force; also a body in motion at constant velocity will stay in motion at constant velocity unless acted on by an unbalanced force
Inertia - the resistance of a body to change its momentum, a body at rest remains at rest, a body in straight line motion will remain so, unless a force is applied against it
