If both the mass and the net force on an object are doubled, then the object's acceleration will not change.
how much force is needed to hold the 2kg object
If a pumpkin has a mass of 2 kg, it actually weighs 19.6 N on Earth. Weight is the product of mass and the local force of gravity on the object.
200N doesn't describe the object, it describes the force acting on an object. If i can correctly assume you are talking about 200N as the weight force of the object, F=MA 200=M(9.8) M=200/9.8 M= a little bit more than 2kg
Depends on the force of gravity; but on Earth, you can assume a gravity of 9.82 Newton / kg - that is, just multiply the mass by 9.82.
If both the mass and the net force on an object are doubled, then the object's acceleration will not change.
Use the formula force = mass x acceleration, to find out the acceleration. Next, velocity = acceleration x time, to find the velocity. Finally, use the formula KE = (1/2) x mass x speed2, to find the kinetic energy.

how much force is needed to hold the 2kg object
Newton's first law: Force = Mass * Acceleration Rearrange: Acceleration = Mass/Force And now to add numbers: Acceleration = 2 Kg/40N Cancels down to 1/20 Which gives: 0.05 m/s^2
If a pumpkin has a mass of 2 kg, it actually weighs 19.6 N on Earth. Weight is the product of mass and the local force of gravity on the object.
The force on the 1kg body is 0.5 Newton. The acceleration of the 2kg mass with a force of 0.5 Newton will be 0.25m/s^2
This is because the weight of an object does not affect the acceleration of that object due to gravity. At Earth's surface, the acceleration due to gravity is roughly 9.8m/s2, regardless of the mass of the object.What does differ with the mass of the object is the force of gravity. Force is equal to mass multiplied by acceleration. So a one kilogram object will fall with a force of roughly 9.8 meters squared per second squared, or 9.8 Newtons (N). A two kilogram object would fall with a force of about 19.6N (2kg * 9.8m/s2). This is why when -NOT- in a vacuum, items of different mass can fall at different rates. The additional force of the more massive object will better counter the force of friction with the air, allowing it to fall faster even though it's acceleration is the same.
No force is needed to keep an object moving. An object with no forces on it keeps moving at a constant speed in a straight line. If there is any force acting on it to make it slow down, then you need just enough force to cancel the first one, in order to keep it moving.
mass is constant 2kg on earth is 2kg on the moon. Weight depends on gravity. W = mg where g is grav. acceleration. Since gravity is less on the moon, then weight is less on the moon for the same object
