There are three key ingredients to work – force,
displacement, and cause
. In order for a force to qualify as having done work on an object, there must be a displacement and the force must cause the displacement.
What are the two factors to determine the amount of work done on an object?
The amount of work done on an object depends on
the amount of force exerted on the object and the amount of distance the object moves
.
What are the factors to be considered in determining work done on an object?
There are three key ingredients to work – force,
displacement, and cause
. In order for a force to qualify as having done work on an object, there must be a displacement and the force must cause the displacement.
Which two factors determine the amount of work done Brainly?
Answer: the work done on a body depends upon two factors:
Magnitude of the force (F), and. The displacement through which the body moves
.
What determines the amount of work?
The work is calculated by
multiplying the force by the amount of movement of an object (W = F * d)
. A force of 10 newtons, that moves an object 3 meters, does 30 n-m of work. A newton-meter is the same thing as a joule, so the units for work are the same as those for energy – joules.
When can we say that work is done in an object?
Answer: Work is said to be done
when a force applied to an object moves that object
. We can calculate work by multiplying the force by the movement of the object.
What is the SI unit for work done on an object?
The SI unit of work is
the newton-meter or joule (J)
.
What two factors determine power?
- Sample Size. Power depends on sample size. Other things being equal, larger sample size yields higher power. …
- Variance. Power also depends on variance: smaller variance yields higher power. …
- Experimental Design.
How do you calculate work angle?
The work W that a force F does on an object is the product of the magnitude F of the force, times the magnitude d of the displacement, times the cosine of the angle θ between them. In symbols,
W = Fd cos θ
.
How is the height of an object determined?
Calculate the height of the object of interest by calculating
“D * tan (theta)
,” where “*” indicates multiplication and “tan” is the tangent of angle theta. For example, if theta is 50 degrees and D is 40 meters, then the height is 40 tan 50 = 47.7 meters, after rounding.
What two factors are involved in work?
The meaning of work in physics is different from that used in everyday life , Work does not mean that a tough task is done , In physics , there are two conditions for work to be done which are
the acting force and the displacement in the direction of the force .
What is the relationship between work and power?
Work is referred to as the process of energy that is transferred to an object’s motion by applying force. It is generally represented as the product of displacement and force. Power is the amount of energy that is transferred in a unit of time. The formula for calculating the force is
Work = Force * Displacement.
How do you solve for powers?
Power is a measure of the amount of work that can be done in a given amount of time.
Power equals work (J) divided by time (s)
. The SI unit for power is the watt (W), which equals 1 joule of work per second (J/s). Power may be measured in a unit called the horsepower.
How do you calculate minimum work?
If minimum work is done, it means that the object has minimum energy at the top of the staircase. As potential energy can’t be zero due to work done by gravity, the only possibility is that kinetic energy is 0. Thus
work done =mg*height raised.
Is the object on which work is done?
Work is said to be done when
force is applied on an object moves through a distance
in the direction of application of force. … When a force acts on an object over a distance, it is said to have done work on the object. Physically, the work done on an object is the change in kinetic energy that that object experiences.
When we say the work is done?
Work is said to be done
when a force moves an object through a distance in its own direction
.
