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

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

To find an object's weight in newtons on Earth, you can multiply its mass in kilograms by the acceleration due to gravity on Earth, which is approximately 9.81 m/s^2. This will give you the object's weight in newtons.


What is mass in kg if the weight is 7 newtons?

To find the mass in kilograms when weight is given in newtons, you can use the formula: mass (kg) = weight (N) / acceleration due to gravity (9.81 m/s^2). Therefore, if the weight is 7 newtons, the mass would be 0.71 kg approximately (7 N / 9.81 m/s^2).


What is the mass of a 1400-N object?

To find the mass of an object given its weight in newtons, you can use the formula: weight = mass x gravity. Rearranging the formula to solve for mass gives mass = weight / gravity. Since the weight is 1400 N and gravity is approximately 9.81 m/s^2, the mass of the object would be 1400 N / 9.81 m/s^2 ≈ 143 kg.


What is the weight in newtons of an object with the mass of 2000 grams?

To find the weight in newtons, you need to convert the mass from grams to kilograms first. Since 1 kg = 1000 g, the mass of 2000 grams is 2 kg. Next, you can calculate the weight using the formula weight = mass * acceleration due to gravity. Acceleration due to gravity is approximately 9.81 m/s^2. Thus, the weight of an object with a mass of 2000 grams is about 19.62 newtons.


If an object's weight on Earth is 75 N what is its mass?

To find the mass of the object, you can use the formula weight = mass x gravity. Given that weight = 75 N and gravity on Earth is approximately 9.8 m/s², you can rearrange the formula to solve for mass: mass = weight / gravity. Therefore, the mass of the object would be approximately 7.7 kg.

How do you compute the weight of an object?

To compute the weight of an object, you can use the formula: weight = mass x gravity. First, determine the mass of the object (in kilograms) and then multiply it by the acceleration due to gravity (9.81 m/s^2 on Earth) to find the weight measured in Newtons.


How do you find the weight when you know the mass?

To find weight when you know the mass, you can use the formula Weight = Mass x Acceleration due to gravity. Simply multiply the mass of the object by the acceleration due to gravity (usually taken as 9.81 m/s^2) to calculate the weight in newtons.


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 a rock hits the ground with a kenetic energy of 33000 J falling from a height of 10 m what is its weight Remember weight is measured in newtons (N) and is equal to mass times gravity?

To find the weight of the rock, we can use the formula Weight = mass * gravity. The kinetic energy at impact can be converted to potential energy at height to find the mass of the rock. From there, we can calculate the weight using the formula Weight = mass * gravity.
