What is the weight of body of mass 20kg on earth?
On Earth, 20kg is 196 newtons or 44.1 lbs.
If you know an objects mass and the force acting upon it you can calculate its acellaration but can you also calculate its maximum velocity If so whats the formula for this?
Yes, you can calculate the maximum velocity of an object if you know its mass, the force acting on it, and the distance it moves. The formula to calculate the maximum velocity is v = sqrt(2 * F * d / m), where v is the velocity, F is the force, d is the distance, and m is the mass of the object.
What is the sum of an object's mass and velocity?
Mass and velocity are dimensionally different. They cannot be added.
What is the mass of an object multiplied by its velocity?
The product of an object's mass and velocity is known as momentum. Momentum is defined as mass times velocity and is a vector quantity, meaning it has both magnitude and direction. It is often denoted by the symbol "p."
How do you calculate force when mass and velocity are given?
Force equals the mass times the rate of change of the velocity.
Is 20kg of lead heavier than 20kg of feather in vacuum?
No, 20kg of lead and 20kg of feathers would have the same mass in vacuum since both are 20kg. Gravity does not affect mass.
How does momentum work?
Momentum is a property of an object in motion that is determined by both its mass and velocity. The momentum of an object can be calculated by multiplying its mass by its velocity. In the absence of external forces, the total momentum of a system remains constant.
What is the weight of body of mass 20kg on earth?
On Earth, 20kg is 196 newtons or 44.1 lbs.
How fast does the Angel Falls flow?
Everything falls at the same speed :P mass doesn't change velocity
If you know an objects mass and the force acting upon it you can calculate its acellaration but can you also calculate its maximum velocity If so whats the formula for this?
Yes, you can calculate the maximum velocity of an object if you know its mass, the force acting on it, and the distance it moves. The formula to calculate the maximum velocity is v = sqrt(2 * F * d / m), where v is the velocity, F is the force, d is the distance, and m is the mass of the object.
Is terminal velocity depends on mass of object?
No, terminal velocity does not depend on the mass of the object. Terminal velocity is the maximum speed an object can reach when the force of gravity is balanced by the force of drag. This means that all objects, regardless of their mass, will eventually reach the same terminal velocity in a given medium.
If a scooter has a mass of 20kg and a velocity of 18 ms north what is the magnitude o its momentum?
The momentum of an object is given by the product of its mass and velocity. In this case, the scooter's momentum would be 20 kg * 18 m/s = 360 kg m/s. The magnitude of its momentum is 360 kg m/s.
What energy does the falling rock have?
The falling rock has kinetic energy due to its motion as it falls. This energy is the result of its velocity and mass, and it can be calculated using the formula KE = 1/2 * mass * velocity^2.
When are the displacement velocity and acceleration equal to zero for the motion of a mass on a spring?
The displacement is zero at the equilibrium position, the velocity is zero at the maximum displacement points, and the acceleration is zero at the equilibrium position and maximum displacement points.
Is 20kg lead in a vacuum heavier than 20kg feather in a vacuum?
No, both objects have the same mass of 20kg. In a vacuum, there is no air resistance or buoyant force acting on the objects, so they would fall at the same rate under gravity.
What force is required to hold up an object of mass 20kg?
The force required to hold up an object of mass 20kg is equal to its weight, which is 20kg multiplied by the acceleration due to gravity (around 9.8 m/s^2). Therefore, the force required is approximately 196 newtons.
What is the weight of a 20kg box on earth in newtons?
The weight of a 20kg box on Earth is approximately 196.2 Newtons. This is calculated by multiplying the mass (20kg) by the acceleration due to gravity on Earth (9.81 m/s^2).
