If the body is moving with uniform speed no force acting on it Is it true or false?
If Newtonian physics are taken to apply, then I believe that F=ma can be taken to apply in all cases and therefore if a ( acceleration ) is zero it must follow that there is no NETT Force applied to the object of mass m.
The key point here is NETT ... and so I believe that the statement that there is 'no Force applied' as an english-language term is incorrect. It is often the case that two or more balancing forces may apply . These may cancel each other out.
This happens more often than may seem the case at first thought, as in an accelerating aircraft. The aircraft may accelerate until the drag caused by pushing through the air, trying to slow the aircraft , exactly balances the force ( thrust ) from the engines, resulting in a settled and stable speed. This stable speed denotes zero acceleration by definition.

What net force is needed to maintain a 1000 kg in uniform motion for 30 minutes without friction?
Uniform motion is what happens in the absence of any net force, so force isn't needed to maintain uniform motion. But in our everyday experience on Earth, we always need to supply force in order to keep something moving, only because there are always forces acting to stop it, and we have to counteract them. In the case of your 1,000-kg car, we'd have to know what forces are working against it ... wind, road friction, air resistance, wheel-bearing friction, etc. ... and then we'll know how much force we have to supply to cancel those out. Whatever the answer is, it'll be a continuous thing. The length of time will be irrelevant.
What is the net electrostatic force acting on a charged particle located inside a shell of uniform charge?
The net electrostatic force acting on a charged particle located inside a shell of uniform charge is zero. This is because the electric field inside a uniformly charged shell is zero, meaning there are no forces acting on the charged particle from the shell itself.
Describe each force that are acting on a moving object?
forces of body depends on the path it is moving for example if it is moving in straight path it under go forces like frictional forces and forces applied on it if the body is moving in slant path it has frictional force,acceleration due to to gravity(which acts down wards)
True of false The acceleration of an object is inversely proportional to the net force acting on it?
False. The acceleration of an object is directly proportional to the net force acting on it. Newton's 2nd Law: F = ma where F is the force, m is the mass, and a is the acceleration. __________________________________________________ The acceleration of a body is "inversely" proportional to its mass.
What is the effect of acceleration on an object which is not moving?
An object which is not moving is not experiencing any acceleration, other than the acceleration due to gravity, which, along with mass gives it its weight. The upward force (normal force) acting on the object is equal to but opposite to its weight, and all of the forces acting on the objects are in equilibrium so the net force is zero Newtons.
What is the net force acting on a body if body is moving with uniform velocity?
If a body is moving with uniform velocity, the net force acting on it is zero. This is in accordance with Newton's first law of motion, which states that an object will remain at rest or in uniform motion unless acted upon by a net external force.
What is force acting on a body with uniform motion?
A body in uniform motion has no net force acting on it. That means that either there are no forces at all, or else that all the forces acting on it add up to zero.
What force is acting on a body moving with uniform speed on a perfectly smooth road?
1) There are always frictional forces, which by themselves would slow the car down. 2) Since we are assuming that the car is moving at a uniform speed, there must be another force to compensate for the friction, and in the opposite direction (pulling the car forward). This force is related to the effort done by the engine.
Objects moving at a constant speed in a straight are said to be in?
Objects moving at constant speed in a straight line are said to be in equilibrium. That is there is no force acting on them. If a force was acting there would be aceleration and the velocity would change.
A force will make a moving object slow down or stop true or false?
True. A force acting in the opposite direction to the motion of a moving object will slow it down or stop it. This is known as friction or drag.
What is the direction of the centripetal force acting on a satellite that is in uniform circular motion around Earth?
The centripetal force acting on a satellite in uniform circular motion around Earth is directed towards the center of Earth. This force is necessary to keep the satellite moving in a circular path instead of following a straight line.
Is centripetal force is acting when ab body is moving in stright line?
No, centripetal force is not acting when a body is moving in a straight line. Centripetal force is required to keep an object moving in a curved path.
Is an object as 0 net force acting on it then was could you say about its motion?
You could say that its motion is uniform, meaning that its speed is constant,and that it's moving in a straight line.
Objects at rest or in uniform motion have what acting on them?
zero net force
Which direction is the centripatel force acting for a body n uniform circular motion?
The centripetal force for a body in uniform circular motion is directed towards the center of the circle around which the body is rotating. It is responsible for keeping the body moving in a curved path rather than in a straight line.
When an object floats on water there is no gravity acting on it is that true or false?
False. Gravity is always acting on an object, but when an object floats on water, the buoyant force provided by the water is equal to the gravitational force acting on the object, causing it to float rather than sink.
Discuss if a body moving with uniform velocity is in equilibrium?
A body moving with uniform velocity is in equilibrium when it moves with uniform velocity as no acceleration i.e. no net force acts on the body.The sum of all forces must be zero in this case. (To avoid rotation, the sum of all torques must also be zero).
