Newton's First Law: objects at rest tend to stay at rest, objects in motion tend to stay in motion. When the brakes are applied, the friction with the road surface is the force that stops the car -- on ice, this friction is greatly reduced.
The force with which Earth attracts a body of mass 1kg on its surface is approximately 9.81 Newtons.
98.07 newtons (Force = mass x acceleration)
Newtons is a measure of Force and Kilograms of mass, so this conversion only has sense for a particular gravitational field. On earth's surface a mass of 1 Kg exerts a force a force of approximately 9.8 Newtons, so 125 Kg exert a force of approximately 1225 Newtons. Using the conversion 1 Kg to 10 Newtons is also widely accepted in some fields, so you could approximate it to 1250 N
to weigh 1000 newtons the object would have to weigh the equivalent of 100kg Comes from F = ma Force = 1000 newtons = mass x acceleration acceleration = gravity = 10 m/s^2 So Force/acc. = mass = 100 kg
the atmosphere if by "surface gravity", you mean the potential energy forced upon us by gravitational pull, then it's joules. If you mean the actual force of the gravity, it's newtons. (also known as our weight.)
150lbs is 667.2 Newtons at Earth's surface.
1,000 pounds is about 4448 Newtons at Earth's surface.
52 kg is 510 Newtons at Earth's surface.
The mass of 19.6 Newtons is 1.99 kilograms at the earth's surface.
A 25kg mass at the earth's surface weighs 25 x 9.8 Newtons = 245 Newtons
400 N at the earth's surface is 40.8kg
The pound is a unit of weight, which is the force that gravity exerts on an object on earth's surface, and the newton is a unit of force defined metrically. Since weight is the result of an object's acceleration by the force of gravity (yes, the idea of acceleration applies to a stationary object), they are directly comparable. One pound [of force] equals 4.44822162 newtons, so 100 pounds equals 444.822162 newtons. For any object in one frame of reference for all measurements, pounds and newtons can be converted one to another in this way.
1 pound is 4.448N (at earth's surface).
On Venus, the acceleration due to gravity is about 8.87 m/s^2. Since weight (in newtons) is equal to mass (in kg) multiplied by acceleration due to gravity, the weight of 1 kg on Venus would be 8.87 newtons.
A mass of 1.5 kg weighs 14.7 newtons (3.31 pounds) on the surface of the earth, and 2.4 newtons (8.6 ounces) on the surface of the moon.
The force with which Earth attracts a body of mass 1kg on its surface is approximately 9.81 Newtons.
The force of gravity on 1 kilogram of mass on the Earth's surface is approximately 9.8 newtons.
