What else can I help you with?
Write the formula for the work done on a body when a force acts on the body in the direction of its displacement?
WORK = FORCE x DISPLACEMENT
If an unbalanced force acts on a body what will happen?
If an unbalanced force acts on a body, it will cause the body to accelerate in the direction of the force. The acceleration will be directly proportional to the magnitude of the force and inversely proportional to the mass of the body, as described by Newton's second law of motion (F = ma).
What is present when work is done?
When work is done, energy is present. Work involves the transfer or conversion of energy from one form to another, such as mechanical work moving an object or chemical work changing the composition of a substance.
How can you relate a force with the change of a momentum of a body?
Change of the body's momentum = (force on the body) x (length of time the force acts on it)
How can you related of force with the change of momentum of a body?
Change of the body's momentum = (force on the body) x (length of time the force acts on it)
How can you relate a force with the change of momentum of a body?
Change of the body's momentum = (force on the body) x (length of time the force acts on it)
Does an action -reaction force pairs acts on the same body?
Reaction pairs work on the same things and in opposite directions.
Can a centripetal force ever do work on an object. explain?
Centripetal force refers to the force that acts on a body moving in a circular path. It does not do work on an object because it acts perpendicular to the motion of the body. The work done on a rotating object is zero.
What is the size of the force multiplied by the distance through which the force acts?
Work W. The dot product of Force and Distance through which the force acts is called Work . W=F.d
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 the work done against the gravity when a body is moved horizontally along a frictionless surface?
No work is done against gravity when a body is moved horizontally along a frictionless surface because the force of gravity acts perpendicular to the direction of motion. Work is only done when a force is exerted in the direction of motion.
Which term is defined as the size of the force multiplied by the distance through which the force acts?
The term defined as the size of the force multiplied by the distance through which the force acts is work. Work is calculated as the force applied in the same direction as the displacement multiplied by the distance moved.
