If you need to include the effects of air resistance, then the answer is more complicated
than you want to deal with.
If you're satisfied to ignore air resistance, then the weight doesn't make any difference. We've known
for the past 600 years that without air resistance, all objects fall the same. Where have you been ?
An object that falls from a height of 'H' hits the ground at a speed of sqrt(2GH).
If 'H' is in meters, then the speed is sqrt(19.6H) meters per second.
If 'H' is in feet, then the speed is sqrt(64.4H) feet per second.
What else can I help you with?
How do you clculate the speed of an object if you know the mass and work?
You cannot directly calculate the speed of an object knowing only its mass and work. Speed is determined by the object's kinetic energy, which is related to both its mass and velocity. To calculate speed, you would need more information such as the object's kinetic energy or the distance traveled.
When work is not done to an object?
The object continues moving in a straight line at its current speed.
When work is done to an object?
The object continues moving in a straight line at its current speed.
How does the work from a constant force affect the motion of an object?
The work done by a constant force on an object affects its motion by changing its speed or direction. If the force is in the same direction as the object's motion, it can increase its speed. If the force is in the opposite direction, it can slow down or stop the object. The work done by the force can also change the object's kinetic energy, which is related to its motion.
Why Does kinetic energy increase as speed increases?
Kinetic energy is directly proportional to the square of an object's speed. As speed increases, the object has more momentum and therefore more kinetic energy. This is because kinetic energy is a measure of the work required to accelerate an object to a certain speed.
Is velocity the speed of an object and its direction of motion?
Yes, without the direction it is just speed
What happens when work is done on a object?
When work is done on an object, it gains energy in the form of kinetic energy or potential energy depending on the type of work done. The object's speed, height, or deformation may change as a result of the work done on it.
Can you work out the speed of an object by using mass and distance?
No, the speed of an object cannot be determined solely by its mass and distance. Speed is calculated as the distance an object travels over a specific time period. To determine an object's speed, you would need to know both the distance it has traveled and the time it took to cover that distance.
Can speed travel in what density?
It doesn't work that way. For a start, speed doesn't travel. Rather, an object travels at a certain speed.
What must happen to an object if a force does work on it?
If a force does work on an object, the object's energy changes. The object will either speed up, slow down, or change direction depending on the direction of the force. Work is done when a force causes a displacement in the object's position.
Why do magnetic forces do no work?
Magnetic forces do no work because they act perpendicular to the direction of an object's movement, meaning they do not transfer energy to the object to change its speed or direction.
What is the work done by a machine on an object?
The work done by a machine on an object is the transfer of energy that results in a change in the object's position, speed, or shape. It is calculated by multiplying the force applied by the machine on the object by the distance the object moves in the direction of the force. Work is typically measured in joules (J).
