What is Kilojoule?
A kilojoule (or Calorie) is a unit of energy.
In Australia, we use kilojoules (kJ) to measure how much energy people get from consuming a food or drink.
The kilojoule content of foods depends on the amount of carbohydrates, fats and proteins present in the food, and the portion size..
Is kg/m s the same as NS?
The newton-second (also newton second; symbol: N⋅s or N s) is the derived SI unit of impulse. It is dimensionally equivalent to the momentum unit kilogram-metre per second (kg⋅m/s). One newton-second corresponds to a one-newton force applied for one second.
What is a joule equal to in terms of kg M and S?
Practical examples. One joule represents (approximately): The kinetic energy of a 2 kg mass traveling at 1 m/s.
How do you convert kg to joules?

What do you mean by 1 nm work is said to be done?
Thus from the above equation we can conclude that when a force of 1 Newton (N) is applied on an object and as a result the object gets displaced by an amount of 1 m, then the net work done on the object will be 1 Nm. We denote the quantity of work by the unit Joule (J) 1 Joule = 1 Newton meter.
How many joules is 60 watts?
Consider a 60 Watt light bulb. A 60 Watt bulb uses 60 Joules of energy each second it is on.
What is work formula?
Work is done when a force that is applied to an object moves that object. The work is calculated by multiplying the force by the amount of movement of an object (W = F * d).
What is 200 joules in KG?
Convert 200 Joules to Kilogram-force Meter200 Joules (j)20.394 Kilogram-force Meter (kgfm)1 j = 0.101972 kgfm1 kgfm = 9.807 j
How many joules does it take to move a car?
Ek = ½ x 10 kg x (20 m/s)2 = 2000 Joules When moving objects be stopped, all their kinetic energy must be transformed into another form of energy. Work done to stop object = kinetic energy lost. A car moving at 100 km/h has 4 times as much kinetic energy as a car moving at 50 km/h.
What is positive work?
Answer: Positive work: when force and displacement are in the same direction, the work performed on an object is said to be positive work. … Negative work: Negative work is performed if the displacement is opposite to the direction of the Force applied.
Is 1 Joule a lot?
This is due to the fact that a joule is an extremely small amount of energy. To put how small a joule is into perspective, a liter of gasoline has 31,536,000 joules of energy in it. A kilowatt-hour is equal to 3,600,000 joules.
What unit is kg/m s?
The kilogram-meter per second (kg · m/s or kg · m · s -1 ) is the standard unit of momentum . Reduced to base units in the International System of Units ( SI ), a kilogram-meter per second is the equivalent of a newton-second (N · s), which is the SI unit of impulse .
What is a joule per kilogram?
Joule Per Kilogram (J/kg) is a unit in the category of Thermal heat capacity. … This unit is commonly used in the SI unit system. Joule Per Kilogram (J/kg) has a dimension of L2T-2 where L is length, and T is time. This unit is the standard SI unit in this category.
What is 1 kg in Newtons?
9.80665Kilogram is the base unit of mass in the metric system. 1 kilogram or kilogram-force (kg or kgf) = 9.80665 newtons (N) = 35.2739619 ounces (oz) = 1000 grams (g) = 1000000 milligrams (mg) = 2.20462262 pounds (lbs) = 0.157473044 stones (st).
How many grams are in a Joule?
How many grams in 1 joule/metre? The answer is 101.97162129779. We assume you are converting between gram-force and joule/metre. You can view more details on each measurement unit: grams or joule/metre The SI derived unit for force is the newton.
What is the unit of KG M s2?
Force in terms of base units is defined is kg m/s2 in SI and lbm ft/s2 in Am.
How much is 1 Joule in Watts?
Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s) which means that 1 kW = 1000 J/s. A Watt is the amount of energy (in Joules) that an electrical device (such as a light) is burning per second that it’s running. So a 60W bulb is burning 60 Joules of energy every second you have it turned on.
What is the formula of Joule?
In words: Work is equal to the force that is exerted times the distance over which it is exerted. In equation form: work (joules) = force (newtons) x distance (meters), where a joule is the unit of work, as defined in the following paragraph.
What do you mean by 1 Joule?
Joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. … In electrical terms, the joule equals one watt-second—i.e., the energy released in one second by a current of one ampere through a resistance of one ohm.
What is the SI unit for latent heat?
SI unit jouleis a measure of the heat energy (Q) per mass (m) released or absorbed during a phase change. is defined through the formula Q = mL. is often just called the “latent heat” of the material. uses the SI unit joule per kilogram [J/kg].
Is a Newton a kg MS 2?
Definition. One newton is the force needed to accelerate one kilogram of mass at the rate of one metre per second squared in the direction of the applied force.
