How do you solve a weight problem in physics?
The equation used to calculate the weight of an object is F = ma. “F” is the force in Newtons, “m” is the mass in grams and “a” is the acceleration due to gravity. Put the values of the problem into the equation. For example, multiply the mass of the object times the acceleration due to gravity, or F=(3g)(9.81 m/s^2).
How do you solve for mass and weight?
It depends on the object’s mass and the acceleration due to gravity, which is 9.8 m/s2 on Earth. The formula for calculating weight is F = m × 9.8 m/s2, where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms.
How do you find weight from mass in physics?
To find an object’s mass using its weight, the formula is Mass equals Weight divided by the Acceleration of Gravity (M = W ÷ G). Convert the weight measured in pounds to the equivalent in Newtons. In the formula for determining mass based on weight, mass is measured in Newtons.
What is the weight force of a car has a mass of 800 kg take g 9.81m SEC?
Solution, The weight force of the car will be 7848 N.
What is the formula for weight in physics?
The weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity, w = mg.
What is the acceleration of a 50 kg object pushed with a force of 500 newtons?
Answer: The acceleration will be 10 m/s^2.
What is the force of gravity on a body of mass 150 kg lying on the surface of the Earth?
F= 1472 N. Q. Give reason for the following : The force of gravitation between two cricket balls is extremely small but that between a cricket ball and the earth is extremely large.
How much weight can a man lift in the Jupiter if he can lift 100 kg on Earth calculate?
Given at Jupiter acceleration due to gravity() is equal to 3 times of acceleration due to gravity on the Earth(). Here m= 100 kg is the mass and it remain same on both earth and Jupiter. W = 2940 N. Thus, the weight of 100 kg rock on the Jupiter is 2940 N.
What is the weight in newtons of an object that has a mass of 10 kg?
for a mass m = 10kg on Earth it`s weight is W = mg = 10 x 10 = 100N.
What is the weight in newtons of a 250 g mass at the surface of the earth?
W = 250 grams = 0.25 kilograms = 2.4517 Newton. g = 9.8 m/s2.
What is the weight in N of an object with a mass of 35 kg?
35 kg⋅9.8 m/s2=343 N . The distance here is 12 m=0.5 m . Note that I used g=9.8 m/s2 to calculate the weight of the box.
How much would a 40 kg object weigh on the Moon?
On the moon that 40 kg child would have a weight of 6.64 Newtons (kg multiplied by gravity) because the moon’s gravity is 1/6th of the Earth’s gravity. Your mass on any planet on the solar system (Jupiter, Venus, Earth, or anywhere else) is the same because the amount of matter in you does not change.
How much does a 40 kg object weigh on Earth?
Note that in the metric system of units, a kilogram (kg) is a unit of mass, not weight. If an object has a mass of 40 kg on Earth it will have the same mass on the Moon. But, on a scale on Earth the 40 kg mass will weigh about 88 pounds.
What is the weight of 40 kg mass of a man on the surface of the earth?
Hence, the weight of the 40 kg mass is 392 N.
What is the weight force of a car has a mass of 800 kg ?( Take?
F = 7840 Newton.
What is the weight of a person with a mass of 80 kg A on the earth assuming g 9.8 M s2 and B on the moon where the acceleration due to gravity is roughly 1.6 m s2?
We would take the mass given, 80 kg, and multiply it times the acceleration of Earth’s downward pull on that mass, 9.8 m/s/s. So the weight on Earth is 784 newtons. So the weight of the same 80 kg mass on the moon is 133.28 N.
What is the weight of a body whose mass is 20kg ?( Take g 10ms 2?
Answer. Weight is equal to the mass of the object multiplied by the gravitational field strength. Gravitational field strength on Earth is nearly 10 ms-2 so the object would weigh 200 Newtons.
Is it accurate to say that a substance with a mass of 1 kg weighs 2.2 lb Why or why not?
Answer and Explanation: It may be accurate to say that an object with a mass of 1 kg weighs 2.2 lb, if the object was weighed at the same location in space. The gravity on Earth is said to be the same everywhere so if both values were measured on Earth then it would be accurate to say so.
What will be the weight of an object whose mass is 15 kg?
Hence, the weight of the object on the Moon is 25 N.
What is the mass of an object that weighs 500 N on the earth what will its mass and weight be on the moon?
A Newton is a force, not a weight and not a Mass. So if a force of 500 Newtons was acting on you on the surface of the moon then using Olivia’s Equation your mass is 312 kg. That mass would also weigh 312 kg on the moon but it would weigh more on Earth Because the force acting on it would be greater!
How quickly would a 70kg object accelerate if the person applied a 500N force?
10. How quickly would a 70kg object accelerate if the person applied a 500N force? 7.14 m/s2.
What is the acceleration of 20n and 5kg?
And, M=5kg. So, 20=5*a (HERE a= ACCELERATION) 20÷5=a. ∴a=4. ∴The acceleration of the object is 4m/s.
How much force is needed to accelerate a 1000 kg at a rate of 3m per second squared?
hence, the force needed to accelerate the 1000kg car by 3m/s2 is 3000N .
What is the force of gravity on a body of mass 1 50 kg lying on the surface of the earth?
F=1472N.
