Forces acting on a car when it is still?
It's weight and the reaction force from it's weight. Hope that helps!
What forces are acting on a helicopter when it is still?
When a helicopter is hovering (aka "still") it has the force of gravity pushing "down" toward the Earth and the force of "lift" of the spinning rotor blade(s) pushing against the surrounding air. When the gravitational force is equal to the force of lift the helicopter hovers on the vertical axis.
Is it possible that a force is acting on a body but still the work done is zero . explain giving one example?
yes........ eg: we are standing on earth, gravity (force) is acting everytime, but as no acceleration takes place work done is 0.
How work done against gravitational force?
Lift any object. Grav. force is acting down, you must apply an upward force to lift the object. Work is force applied through a distance, so work is done if you lift it, but not if you hold it still.
Can objects be weightless?
Yes. An object is weightless if gravity is the only force acting on it. (for example, a ball falling in a vacuum) There is no true "weightlessness", because, even if two masses are separated by billions of light years, there is still a gravitational attraction force. There is a distance at which this cannot be felt anymore, but there is still a force.
What is no net force between object and its surroundings?
If there is no net force acting on an object then the movement of the object doesn't change. If it is sitting still, then it remains sitting still. If it is moving, then it continues moving at the same speed in the same direction.
What are the forces acting on sitting still?
The chair in pushing you up and the gravity pushing you down
What is the force exerted by the object you are trying to move?
Its a reaction force, and is equal and opposite to your force, only it is acting on different objects, so the force is still unbalanced.
What are the between balanced force and unbalanced force?
An object with balanced forces acting on it is still. An object with unbalanced forces acting on them moves at an non constant velocity. It is possible for an object to have balanced forces acting on it and yet move in a vacuum.
What is the net force of an object that is sitting still?
Since force is a function of acceleration and an object at rest has zero acceleration, then then net force is zero as well.
What forces are acting on a still car?
on a still car the weight force is down, and is balanced with the reaction force (working upwards). friction of forward and balanced with drag - backwards. ;)
Is it possible for an object not to be in motion and still have a force acting on it?
Yes, the object can have equal forces acting in opposite directions: 5N ->[]<- 5N The object will have forces acting upon it, but will not move.
Forces acting on a car when it is still?
It's weight and the reaction force from it's weight. Hope that helps!
Will there be any force acting on a still body other than the gravitational force?
A still body has to be supported by something so not to "fall." That something is exerting an equal but opposite force to the gravitational pull. The net force is zero, so the body stays still. See Newton's third law of motion.
Why does a skate board stay still?
If an object with wheels (or a round object) is on a level grade, and there is no force acting on it, it will not move.
Example of Balanced Force?
A body is hanging. The forces on it are well balanced. The weight of the body is the force acting downward and the tension in the string acting upward.Same way a body placed on a tableAdd: One example is a book sitting on a table. The book does not move because the gravitational force acting on it in a downward direction is equal but opposite to the upward normal force that the table exerts on the book.The same can be said for a person standing still on a floor. She doesn't move because the downward gravitational force acting on her is equal but opposite to the upward normal force exerted on her by the floor.
When was Sitting Still created?
Sitting Still was created in 1981.
