If a moving body has no acceleration does it mean no force acts on it?

There can well be forces acting on the body. It means that the NET FORCE (the vector sum of all the forces) acting on the object is zero.

it means that sum of all forces cancels each other and the body move in a straight line

Is acceleration due to gravity act on a body resting on a table zero?
no,but the table exerts an equal & opposite force so net force is zero.
What can cause velocity to change?
acceleration, due to a force the moving body is affected by. SUM[Forces] = mass * acceleration --> change in speed.
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).
Will a body remain at rest if no net force acts on it?
If it was initially at rest - yes. If it was initially moving, it will continue moving at the same velocity.
Why acceleration due to gravity 'g' is taken as negative for bodies moving upward?
The acceleration due to gravity is a property of the Earth's mass and radius, and of gravity itself, and doesn't depend on which way something is moving. -- The acceleration produced by a force is always in the direction of the force, and the forces of gravity act along the line between the centers of two objects. -- One force of gravity acts on the body that's up in the air, pulling it ... and therefore accelerating it ... toward the center of the Earth, with acceleration equal to the body's weight/the body's mass = 9.8 meters per second2. -- The other force of gravity acts on the Earth, pulling it ... and therefore accelerating it ... toward the center of the body that's up in the air, with acceleration equal to Earth's weight/Earth's mass. In order to calculate that number, you have to know the Earth's weight. It's the same as the weight of the body that's up in the air, since the forces of gravity are equal in both directions. So once you know the weight of the body on Earth, you know the weight of the Earth on the body, and you can calculate the Earth's acceleration when they're falling toward each other.
What affects the acceleration of a moving body?
Force! Acceleration a=f/m, the force F changes the acceleration.
CENTRIPETAL?
A force that acts on a body moving in a circular path and is directed around the object which the body is moving
What is centriptal force?
Is a force that acts on a body moving in a circular path and is directed toward the center around which the body is moving.
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)
What is A force produces an acceleration of 0.5 m s2 on a body of mass 1 kg What is the acceleration if the same force acts on a body of mass 2 kg?
The force on the 1kg body is 0.5 Newton. The acceleration of the 2kg mass with a force of 0.5 Newton will be 0.25m/s^2
What in centripetal force?
Centripetal force is a force that acts on a body moving in a circular path and is directed toward the center around which the body is moving. It is also known as center seeking force.
Is acceleration due to gravity act on a body resting on a table zero?
no,but the table exerts an equal & opposite force so net force is zero.
What can cause velocity to change?
acceleration, due to a force the moving body is affected by. SUM[Forces] = mass * acceleration --> change in speed.
Why is the body moving with a uniform velocity is zero?
The body is not zero, but the sum of all forces on it is. -- "Uniform velocity" means no acceleration. -- Acceleration is force/mass . -- If acceleration is zero, that's an indication that force must be zero.
If a body is moving with constant velocity is it moving with constant acceleration?
An object moves with constant velocity when there is no net force acting upon it. If there are no forces acting on an object, or if the forces acting on it "cancel out" leaving a net force of zero acting on the object, it will have zero acceleration. With a zero acceleration, the velocity of the object will be constant.
A horizontal force acts a body that is free to move can it produce an acceleration if the force is less then the weight of that body?
Yes it can, and if less force is needed if you eliminate the possibility of friction. You can find many examples of this, but i think this is an excellent opportunity to devise an experiment and practice your scientific methods.
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).
