Does moving an object a greater amount of distance always require a greater amount of work?
No, the amount of work done on an object also depends on the force applied. If a greater force is applied to move an object a shorter distance, the work done could be the same as moving it a greater distance with a smaller force. Work done is the product of force and distance moved in the direction of the force.
Does moving an object a greater distance always require a greater amount of work?
Moving an object a greater distance does not necessarily require a greater amount of work. Work is calculated based on the force applied and the distance moved in the direction of the force. So, if the force decreases as the object moves a greater distance, the work done may not necessarily increase.
How can a lever generate a large force?
A lever works against a fulcrum. If there is a shorter section of the lever at one end of the fulcrum and a longer section at the other end, then you can exert a force on the longer end of the lever, and have a greater force exerted on the shorter end. That is because you are moving the long end through a longer distance than the shorter end moves, and all the force exerted over the longer distance is then effectively compressed into the shorter distance.
What happens when you move the fulcrum?
Moving the fulcrum in a lever changes the mechanical advantage of the system. When the fulcrum is moved closer to the load, it requires less effort to lift the load but the distance the load moves is reduced. Conversely, when the fulcrum is moved closer to the effort, it requires more effort to lift the load but the load moves a greater distance.
Can the distance covered by a moving object ever by zero gess than give an example?
No, the distance covered by a moving object cannot be less than zero. Distance is always measured as a positive value. If an object is moving, it will always cover a distance greater than or equal to zero.

The distance time graph for a faster moving object has a smaller slope than the graph for a slower moving object True or false?
False. The slope of the distance-time graph represents the speed of the object. A steeper slope indicates a faster speed, so the distance-time graph for a faster moving object would have a greater slope than the graph for a slower moving object.
Is the equation that shows distance varying inversely with time true?
No, the equation showing distance varying inversely with time is not true. In reality, distance is directly proportional to time when an object is moving at a constant speed. This relationship is described by the equation distance = speed x time.
How are time and distance related for an object moving at a constant speed?
Time and distance are directly proportional for an object moving at a constant speed. This means that the longer the time taken to travel, the greater the distance covered, and vice versa. The relationship can be expressed using the formula: Distance = Speed x Time.
Why are big wheels better for a mousetrap car?
Because the axle is moving just as many rotations but since the wheels are bigger it's moving a greater distance. Because it's a big wheel, after all the string is gone, the wheels keep moving, which lets your car coast a longer distance.
How can you tell if friction wastes more work on shorter or longer planes?
Friction wastes more work on longer planes because the distance over which friction acts is longer, resulting in more energy lost as heat. This leads to a greater decrease in the mechanical energy of the object moving along the plane.
The slope of a line on a distance time graph represents?
The slope of a line on a distance-time graph represents the speed or velocity. The steeper the line is and the greater the slope of the line is, the faster the object is moving.
What is increase in speed?
An increase in speed refers to the act of moving faster or accelerating. It means covering a greater distance in the same amount of time or reducing the time taken to cover a certain distance.
