1. How much force is required to push an object with a mass of 30 kg a distance of 2 meters? 2. What is the mass of an object that has a weight of 150 N on earth?
3. How much work is done if it takes 980 N of force to lift an object a distance of 2.5 meters?
4. how much power is needed when a crane uses a force of 5.0 X 10^5 N a distance of 3 meters in 150 seconds

Less force and energy was applied

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
