What else can I help you with?
What wouid happen to mass and weight of a body if the force of gravity disappear suddenly?
If the force of gravity were to disappear suddenly, the mass of the body would remain the same, as mass is a measure of the amount of matter in an object and does not change. However, the weight of the body would become zero, since weight is the force exerted on an object due to gravity.
Is the net force acting on a body is zero will the velocity be zero?
Not necessarily. If the net force acting on a body is zero, the body's velocity will remain constant (assuming no other forces act on it to change its velocity), but it doesn't mean the velocity will be zero. If the initial velocity is zero, then the velocity will remain zero if the net force is zero.
Will a body be in equilibrium under action of a single force?
No, a body will not be in equilibrium under the action of a single force. For a body to be in equilibrium, the vector sum of all the forces acting on the body must be zero. A single force cannot balance itself out, so it will cause the body to accelerate in the direction of the force.
The acceleration of a body cannot be zero at a point where?
When a body is rotating in a circular path around an axis.
The force required to maintain an object at a constant velocity in free space is equal to what?
zero! If "free space" is free of forces then the force required to maintain a body at constant speed is zero, because a body at constant speed and direction has zero acceleration and whatever the mass m, f=ma and if acceleration a is zero the force is zero.It takes force to change speed or direction. A body moving around in a circle at constant speed is still changing direction and accelerating and requires force, even if the speed is constant. So you could push the body up to 15 miles per hour and then let go and it would take zero force for the body to maintain 15 miles per hour speed. If you whirled the body on a string up to 15 miles per hour and cut the string , the body would take off in the direction tangent to when the string was cut and go in that direction at 15 miles per hour and it would take zero force to maintain that speed.
Why a body cannot be in equilibrium to single force acting on it?
A body is in equilibrium when the force on it is zero, thus if a single force is on the body, the force must be zero or the body will not be equilibrium.
When a cat sleep on a table the net force on it is?
Net force is defined as the overall force acting on an object. When a cat sleeps on a table, the net force on it is zero. When a body is at rest the net force acting on the body is zero.

If the force of gravity were to disappear suddenly, the mass of the body would remain the same, as mass is a measure of the amount of matter in an object and does not change. However, the weight of the body would become zero, since weight is the force exerted on an object due to gravity.
Why a body cannot be in equilibrium due to single acting on it?
A body is in equilibrium when the force on it is zero, thus if a single force is on the body, the force must be zero or the body will not be equilibrium.
Can the impulse of force be zero even the force is not zero?
Yes, it is possible for the impulse of force to be zero even if the force is not zero. This can happen if the force is applied for such a short period of time that the area under the force-time graph, which represents impulse, is zero.
Is it possible that a body may have non zero mass but zero weight?
Yes, it is possible for a body to have non-zero mass but zero weight when in free-fall or in a microgravity environment where there is no gravitational force acting on the body. Weight is the force due to gravity acting on an object, and so in the absence of gravity, the body would have zero weight but still have mass.
If the net force applied to a body is unchanging the body will?
Accelerate at a constant rate (although if the net force is zero, this constant acceleration would be zero, so it wouldn't really be proper to say its accelerating in that case).
Is the net force acting on a body is zero will the velocity be zero?
Not necessarily. If the net force acting on a body is zero, the body's velocity will remain constant (assuming no other forces act on it to change its velocity), but it doesn't mean the velocity will be zero. If the initial velocity is zero, then the velocity will remain zero if the net force is zero.
What is the net force when the forces are balanced?
Balanced force means two forces are acting on opposite sides of body and that body doesn't change its position.Nothing. Zero newtons. Zilch :L
Will a body be in equilibrium under action of a single force?
No, a body will not be in equilibrium under the action of a single force. For a body to be in equilibrium, the vector sum of all the forces acting on the body must be zero. A single force cannot balance itself out, so it will cause the body to accelerate in the direction of the force.
