If you can keep lifting a 1 kg weight to a height of 1 meter every second, weight after weight after weight, then you will be steadily producing
10 Watts
of power.
How many joules does it take to lift 1 kg?
On earth it takes about 10 Newton-meters (N-m) of energy to raise a 1 kilogram mass to a height of 1 meter. Since 1 N-m equals 1 Joule, that’s
10 Joules
.
How many calories does it take to lift 1 kg?
It takes
~ 240 calories
to raise or lift 100 kilograms 1 meter. Human energy calories are always kilocalories. If you wanted to burn 1000 (k)calories, you’d have to bench press 100kg about 830 reps.
How much work is done when you lift 100 kg of mass by meter?
If you lift 100 kg of mass 1-meter, you will have done
980 Joules
of work.
How much energy does 1 kg have?
This implies, for instance, that 1 kilogram of matter is equivalent to an energy E = (1 kg)×(3×108 m/sec)2 =
9×1016 kg m2/sec2
. An energy of 1 kg m2/sec2 is known as 1 joule, for short. The joule is not a unit of energy that is used much in everyday life.
Can I lose 1 kg a day?
Generally, experts recommend losing around
1–2 pounds
(0.5–0.9 kg) per week, which may involve reducing your calorie intake by around 500–1,000 calories per day ( 12 ). However, losing 1 pound (0.5 kg) per day would likely require you to limit your intake even more.
How can I burn 1000 calories a day?
For some people, these activities may burn more than 1,000 calories. Burning 1,000 calories through exercise alone or in a single exercise session is more difficult, but not impossible. For example, a 150-pound person running at a 10-minute mile pace for 90 minutes burns about 1,020 calories.
How much force is needed to lift a 25 kg?
(Note: The weight of a 25-kg object is approximately
250 N
; it takes 250 N to lift the object up.)
How much work does it take to lift 1kg up 1 meter?
On earth it takes
about 10 Newton-meters (N-m) of
energy to raise a 1 kilogram mass to a height of 1 meter. Since 1 N-m equals 1 Joule, that’s 10 Joules. If it takes 1 second to lift the weight 1 meter, than you have converted 10 Joules of energy to potential energy in one second. That’s 10 Watts of power.
How much work is required to lift a 2 kg mass to a height of 10 meters?
the Work done to life the mass of 2 kg to a height of 10 m is
196 J
.
How much energy is released if 1 kg of mass is lost through radioactive decay?
Nuclear fusion and nuclear fission result in a mass change, Δm, between the starting and end products. The loss of mass produces energy E = Δm c
2
, where c equals the speed of light. As a consequence of this Einstein relation, the mass of 1 kg can be converted into an energy of
about 9 × 10
16
J or 25 × 10
9
kWh
.
How much energy is released when a mass of 1 kg is completely converted into energy?
9×108J
.
What amount of energy is associated with mass of 2.5 kg?
If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of
kilograms-meters squared per second squared
. Kinetic energy is usually measured in units of Joules (J); one Joule is equal to 1 kg m
2
/ s
