Air resistance.
Mass is defined as resistance to acceleration, so one could measure how much force is needed to accelerate the object.
isn't in gravity??
As worded, the question doesn't mean much. I think you want to compare thegravitational force on an object with the buoyant force on the same object whenit's in a fluid.As long as the gravitational force is greater than the buoyant force, the objectmust keep accelerating downward ... sinking further and faster, and displacingmore fluid as it goes. If it ever displaces enough fluid for the buoyant force toequal the gravitational force on it (its 'weight'), then it stops sinking, and floatsright there.
drag force (frictional force exerted by air) or air reststance
When an object is moved by force, work is being done on the object by transferring energy to it. This can result in the object gaining kinetic energy or changing its position. The amount of work done is equal to the force applied multiplied by the distance the object is moved.
Work is applied to an object and the object is moved over a distance in the same direction of the applied force.
In order for work to be accomplished, there must be a force applied to an object and the object must move in the direction of the force. Work is the product of the force applied to an object and the distance over which the force is applied.
resistance force.
work
is moved
The work done is calculated as the product of force and distance moved in the direction of the force. In this case, the work done is 15 Joules (10 N * 1.5 m).
is moved
In order for work to be accomplished according to the scientific definition, a force must be applied to an object, causing it to move in the direction of the force. Work is done when this force causes the object to be displaced.
The object is moved and energy is transferred.
The type of energy is mechanical energy, specifically work. Work is done when an object is moved against a force, transferring energy to the object.
The amount of force multiplied by the distance an object is moved is called work. Work is a measure of energy transfer and is calculated as force multiplied by distance in the direction of the force.
