If you are pushing a car and use less force it will be harder to make the car move.
It has became much harder. The banks are giving out less loan due to recent economy.
Yes, if the fulcrum is closer to the effort, the force required to lift an object will be less because the lever arm is shorter. This creates a mechanical advantage in which less force is needed to move the object.
It would be easier to kick a football on the moon because there would be no air to hold it back. The football would go farther even if less force is applied.
A doorknob has a larger radius, which creates distance from the axis of rotation, allowing for more torque to be applied with less force. An axle typically does not have the same leverage, making it harder to turn with the same force.
It is easier to lift a rock in water because water exerts an upward buoyant force on the rock that helps counteract the force of gravity pulling it down. In air, there is less buoyant force acting on the rock, making it harder to lift.
Having your arms wider apart will yield a smaller magnitude than if your arms were closer together. A resultant with a smaller magnitude means less force to counter your weight, hence a harder pull-up
An empty box has less mass and therefore requires less force to move it. On the other hand, a box full of books has more mass, making it heavier and harder to push because it requires more force to overcome inertia.
This is easier to visualize if you rearrange, solving for acceleration: a = F/m. What this means is that a larger force will produce a larger acceleration. It also means that, since mass is in the denominator, in the case of a larger mass, there will be less acceleration. In other words, a more massive object is harder to accelerate (it is harder to speed it up or slow it down).
No. Mutts are less because they are normally harder to train and easier to breed.
There is a shortboard and a longboard. A shorter board is easier to do tricks on but is harder to paddle/stand up on. A longboard is less maneuverable but easier to surf on.
they will become more crumbly and or harder
Work is easier when you use less force or when,you use a wedge to do less work instead of,using your hand to stop a door from closing or opening.I hope this makes sense.
