How are magnetic and gravitational force alike?
They're alike by both pulling down on something. The only difference is the a certain material is needed for a magnet to use it's magnetic force. Gravity doesn't need anything.
How much effort is needed to lift a 75 N weight using the pulley system?
If you are talking about a simple pulley with the pulley attached and load rope attached to the object then you will need a little more than 75N of force. Lifting an object (at a constant velocity) requires a force equal but opposite the weight of the object. With any simple machine you will need to do more work to overcome friction. If you were to use a single pulley with the pulley attached to the object then you will need a little more than 37.5 N. If you were to use a multiple pulley system then you would need to know the mechanical advantage of the pulley system.
Do you need more or less Force for a heavy object?
Yes
What is the force you need to use in order to lift a mass of 40kilogram?
-- If the 40 kilogram mass is on the Earth, you need about 392 newtons (88.2 pounds).-- If the same mass is on the moon, you need about 64.9 newtons (14.6 pounds).-- If it's inside a space ship with you and your ship is coasting, then you canlift it with ANY force, no matter how large or small. In fact, after you lift it, you'llneed to apply force in the opposite direction in order to make it stop lifting.
Why are you doing the same amount of work lifting a box or pushing it up a long ramp?
because the long ramp decreases the force you need to lift an object, but increases the distance you must move the object
Does work done depends on time what you mean is doing a work in 5 minutes needs more work or doing a work in 10 minutes need more work you mean more newtons?
Newtons is used to measure force, NOT work or energy. It is important not to confuse force with energy (or work). Whether you need more force depends on the exact situation. For example: * When pulling an object in a situation where you have to overcome friction between solids, the force is practically independent of the speed. * When pulling an object through a fluid, the force does increase for a greater speed. * When pulling an object at a constant speed upwards (against the pull of gravity), the force required is independent of the speed (ignoring air resistance).
What are hydraulics used in?
Used where there's a need to produce a greater force using a smaller force. E.g. Car brakes Lifting cars in garages
How does lifting weights help produce denser bones?
Our bodies grow and change as they need to (at least to an extent). If your body is lifting more weight and putting more stress on the bones, it will slowly strengthen the bones to handle the new loads. Its the same reason lifting builds muscle; we need it so our bodies provide.
If you pulling out of your stall and hit someone that is pulling into a stall behind you who is to pay?
Were you backing up? Would need more specific details regarding the facts of loss to be of more assistance.
How CAN altering the mass and acceleration affect force?
According to Newton's second law, force equals mass times acceleration.
Who makes the best weoght lifting workout set?
The Bowflex is good, but it may have more features then you need.
What is a sporting example of static strength?
athletics: the hammer throw, shot put, discus all three need strength and you improve on them the more and more you train. Also in the Olympics: weight lifting, you need a lot of strength and the more you practice the better you get. Hope i answered you question for you.
Which pulley system can make work easier?
A pulley halves the force required to lift a load, but doubles the length of rope or cable. So if you had a 10lb. weight attached to a rope, and were pulling the rope upward, you would need 10lbs. of force to lift it. However, if you had a pulley attached to a beam overhead, and were pulling down on the rope, you would only need 5lbs. of force to move the weight, but you would need to pull twice as much rope to get the weight to move the same distance.
What do you need to know to find out how much work you do when you pick up a cat?
Work is equal to force x distance. So it will depend on how much force you apply to lifting the cat, and also how far off the ground you lift it.
How are magnetic and gravitational force alike?
They're alike by both pulling down on something. The only difference is the a certain material is needed for a magnet to use it's magnetic force. Gravity doesn't need anything.
Suppose the force of friction on a sliding object is 25 N The force needed to maintain a constant velocity is?
100 N===========================Answer #2:That depends on the direction of the pulling force.The horizontal component of the pulling force must be 100 N.So the more steeply the rope angles upward, the harder you'dhave to pull on it in order to create a 100N horizontal component.
How do I learn weight lifting without injuring myself?
To learn weight lifting without injuring yourself you will need to start slowing in the beginning. Do not attempt to much weight to begin with and slowly add more.
