Is work done at a constant speed?
If an object is moving with a constant velocity, then by definition it has zero acceleration. So there is no net force acting on the object. The total work done on the object is thus 0 (that’s not to say that there isn’t work done by individual forces on the object, but the sum is 0 ).
Can acceleration be produced without doing any work give example?
Yes, it is possible that work done is zero even when a body is in accelerated motion. This happens when force is acting in a direction perpendicular to the direction of motion. For example, earth moving around the sun in a circular orbit under the gravitational force perpendicular to its path.
What is the work done in holding a 15 kg suitcase?
What is work done in holding a 15kg suitcase while waiting for a bus for 15 minutes ? Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams. Work done is zero, because displacement is zero.
Is it possible for a body to have acceleration without velocity?
Answer: Yes, an object can have zero velocity and still be accelerating simultaneously. Let us consider an object moving in the forward direction.
Is it possible to have zero acceleration and still be moving?
Yes, an object that was set in motion in the past by some force, but that is no longer being acted on by a net force, is moving but with zero acceleration, i.e. it is moving at constant velocity. For example, a puck sliding along a horizontal plane of ice after being hit with a hockey stick.
Can you go around a curve with constant acceleration?
Can you go around a curve with constant acceleration? No, because the vector always points to the center of the circle and you are always changing the direction of that vector.
Is it possible to accelerate in constant speed?
The velocity vector is constant in magnitude but changing in direction. Because the speed is constant for such a motion, many students have the misconception that there is no acceleration. For this reason, it can be safely concluded that an object moving in a circle at constant speed is indeed accelerating.
