When we calculate the net force acting on the object in these situations, we use the formula… FNET = Fa + Ff

When you want to calculate the acceleration of an object, always use the net force acting on it. FNET = ma

We need to think of the net force as the force pushing down on the scale causing it to give a reading. for example- The elevator pushing up on me will make me push down on the floor (Newton's 3rd Law). We will show this by making the acceleration (3.0m/s2) a negative value. The formula for this would look like this… FNET = Fg + Fa

Mass is determined by using the Newtonian formula m = F/a, where 'm' is mass, 'F' is force or weight in Newtons and 'a' is acceleration. On Earth, the force of gravity or acceleration, is 9.8 meters per second squared. So, given an object with a weight of 1200N, the formula will be m = 1200 / 9.8 resulting in a mass of about 122.45kg (rounded).

Weight = mg, where m is mass in kg and g is acceleration due to gravity, 9.8m/s2. As an example, the weight of an object with a mass of 25kg would be 25kg x 9.8m/s2 = 245kg•m/s2 = 245N.

How do you find an object's weight in newtons on earth?

Multiply its mass in kg times 9.814 m/sec, which is its gravity acceleration on earth.


How to find the weight of a 15 kg rock Acceleration due to gravity is 9.8 ms2?

Weight in a certain place = (mass of the object) x (acceleration of gravity in that place)Weight of that rock, on Earth = (15 kg) x (9.8 meters/sec2) = 147 newtons


How do you find force if you have the weight?

Weight is a force. It is described as the gravitational force acting on an object. It is measured in newtons. If you are thinking of the mass (measured in kilograms for instance) then you multiply by the acceleration due to gravity. Weight = g x mass.


How do you find the weight of an object using its mass?

Multiply the object's mass by the acceleration of gravity in the location where the object is presently. Example: Mass = 5 kilograms Acceleration of gravity on earth = 9.8 m/sec2 Weight = (5 x 9.8) = 49 newtons. Since the weight depends on the local gravity, the same mass has different weights in different places.


How do you find the gravitational potential energy if you have the weight in newtons and the acceleration and the height?

The gravitational potential energy is the product of (mass) x (acceleration due to gravity) x height). The first two terms ... (mass) x (acceleration due to gravity) ... are the object's weight. So if you already know its weight, then the gravitational potential energy is just (weight) x (height) and you don't need to use gravity at all.

If someone weighed 85 pounds on Earth how much would they weigh on the moon in newtons?

To find your weight on the Moon, we have to divide 9.8 (gravity on the Earth) by 6. That answer has to be multiplied by 85 pounds. that answer is done in newtons as you are finding the weight on the moon. newtons is unit for weight.

How do you find the weight of an object on earth?

You could weigh it against other objects. If it is not on the surface, multiply its mass by the acceleration of gravity (at that distance) to find its gravitational potential in newtons.

How do you find the mass of an object given the weight and volume?

If you know the force of gravity then mass = weight/gravitational force. If you don't then you cannot. Knowing the volume is useless.
