Does it take more force to move an object at a faster speed over the same distance?
Yes, a way to move an object faster over a equal distance, is to apply more force, for example: There are two race tracks at a distance of 50m, there are also two runners, one runner is much faster than the other, which will get to the end of the race track faster? The answer is obvious, the runner who has a higher speed/ force is faster. the way to measure the speed of an object is to take the distance and divide it by the time, so an object that travels 10 cm in 5 seconds is moving at a speed of 2cm/s Any object with a greater force working on it will move quicker than another with less force, even if it is the same distance. Hope this helps x.
Technically, force and speed are independent. Force determines the rate of _acceleration_, but not the speed. If an object moves for 5 meters at a constant speed of 1 m/sec, Newton’s first & second laws say that NO NET FORCE is acting on the object. The same is true for the object moving at a constan 3 m/sec. But note, this doesn’t necessarily mean you don’t have to push it! For most “everyday” objects in motion, there is a force of friction which opposes the object’s motion. In order to make the “net force” come out to zero, you would have to push _forward_ on the object by exactly the same amount that friction is pushing backwards on it. Some types of friction (e.g. air friction) are dependent on speed. In those cases, the 3m/sec object would encounter more friction than the 1m/sec object, and therefore to maintain its constant speed you would have to give a greater opposing push to exactly cancel the friction. Other types of friction (e.g. sliding friction) are more or less independ
