If an object with a mass of 20kg is lying on the floor of a lift and the lift accelerates downwards at 4ms calculate the magnitude of the force exerted by the floor of the lift on the object?
The answer would be 80kg/ms or 80N because: force= mass x acceleration = 20kg x 4ms =80kg/ms =80N
How does momentum work?
Momentum is the product of the mass and velocity of an object. Momentum= Mass x Velocity. When the object weighs 20kg and is traveling at 20m/s North it will have a momentum of 400kgm/s North.
What is the density of an object that has a mass of 20kg and a volume of 50l?
You would need to defineTemp and pressure to determine the volume of a liter. Then density = kgm/vol
Is 20kg lead in a vacuum heavier than 20kg feather in a vacuum?
No. Weight = mass x gravity, so for the same mass, you get the same weight.
Object has a mass of 20 kg what is the force of gravity acting on it on earth?
F=ma mass of object = 20kg acceleration due to gravity = 9.81m/s^2 F=20*9.81 F=196.2 kgm/s^2 or 196.2 N
If an object with a mass of 20kg is lying on the floor of a lift and the lift accelerates downwards at 4ms calculate the magnitude of the force exerted by the floor of the lift on the object?
The answer would be 80kg/ms or 80N because: force= mass x acceleration = 20kg x 4ms =80kg/ms =80N
If an object had a mass of 20kg what is the force of gravity acting on it on earth?
If an object with a mass of 20 kg is on the surface of the earth or near it, then the object and the earth are attracting each other with a force of 196 newtons (44.1 pounds).
How does momentum work?
Momentum is the product of the mass and velocity of an object. Momentum= Mass x Velocity. When the object weighs 20kg and is traveling at 20m/s North it will have a momentum of 400kgm/s North.
What is the weight of body of mass 20kg on earth?
On Earth, 20kg is 196 newtons or 44.1 lbs.
What is the mass of an object with a potential energy of 980 J and a height of 5 meters?
PE=mgh 980=mx9.81x5 m=20kg
What is the density of an object that has a mass of 20kg and a volume of 50l?
You would need to defineTemp and pressure to determine the volume of a liter. Then density = kgm/vol
Hom much does a 20kg box weigh in newtons?
An object with a mass of 20 kg weighs about 196 Newtons (44 pounds) on earth.
Is 20kg lead in a vacuum heavier than 20kg feather in a vacuum?
No. Weight = mass x gravity, so for the same mass, you get the same weight.
What is the gravitational force between a mass of 20kg and a mass of 100kg that are 15 meters apart?
The gravitational force between a mass of 20kg and a mass of 100kg that are 15 meters apart is:F = 5.9326933333333E-10
If an object has a mass of 20kg on earth what is the mass of the object on moon?
The mass on the moon will remain the same, 20 kg If the object's mass is 20 kg, then it's 20 kg. On Earth, on the moon, on Mars, or floating weightless in a space ship coasting from one of them to another. Weight depends on where you are, but mass doesn't.
Object has a mass of 20 kg what is the force of gravity acting on it on earth?
F=ma mass of object = 20kg acceleration due to gravity = 9.81m/s^2 F=20*9.81 F=196.2 kgm/s^2 or 196.2 N
What is the weight of 20 kg in object in Newtons?
20kg on earth has a force of 196N
