Do inclined planes help you use less force over a shorter distance?
It's either LESS force over a GREATER distance or MORE force over a SHORTER distance.
Is 5 over six greater than or less than 1 over 6?
It is greater than 1 over 6
Is 5 over 12 greater than less than or equal to 2 over 6?
greater than
Is 12 over 36 greater less than or equal to 12 over 24?
Less than.
Is 3 over 10 greater or less then 0.38?
It is less. It equals 0.30.
Why do machines the less force to do the same amount of work?
Because machines allow force to be applied over a greater distance.
Do inclined planes help you use less force over a shorter distance?
It's either LESS force over a GREATER distance or MORE force over a SHORTER distance.
What machines can change the direction of a force?
Some machines that can change the direction of a force include pulleys, levers, gears, and ramps. These machines can redirect the applied force to achieve a specific mechanical advantage or desired output.
Does an inclined plane lift a heavy load by using more or less force over distance greater?
Less
Is it true or false that in some machines the output force is greater than the input force?
True. In machines like levers, pulleys, and hydraulic systems, the output force can be greater than the input force by utilizing mechanisms that increase the force or decrease the distance over which the force is applied.
When we use a simple machine do we do less work?
Simple machines make work easier by allowing us to apply force over a greater distance, but the amount of work done remains the same. This means that while we may exert less force when using a simple machine, we still need to exert the same amount of work.
How is time inversely proportional to force?
Time is inversely proportional to force because the less time it takes to apply a force, the greater the force exerted. This relationship is described by the formula Force = mass * acceleration, where if the acceleration (change in velocity over time) is greater, a greater force is exerted in a shorter period of time.
What does it mean when someone says Simple machines make work easier?
Simple machines are mechanisms that require only one input force to accomplish specific tasks, such as lifting or moving objects. By using simple machines, individuals can apply less force over a greater distance to achieve the same amount of work. In essence, these devices reduce the amount of effort needed to perform tasks, making work more manageable and efficient.
Do machines increase distance over which force acts?
Machines do not increase the distance over which a force acts. Machines simply allow us to apply a force over a longer distance, but the total work done remains the same. The mechanical advantage of a machine may amplify input force, but the distance over which the force acts remains constant.
Is pressure greater if the force acts over a greater surfice?
No, pressure is not greater if the force acts over a greater surface area. Pressure is defined as force per unit area, so as the surface area over which the force is applied increases, the pressure decreases. This is because the same force is being distributed over a larger area.
What is an example of a machine that allows force to be applied over a greater distance?
A lever is an example of a machine that allows force to be applied over a greater distance. By using a lever, a smaller force applied over a longer distance can produce a greater force over a smaller distance on the other side.
Who is greater the applied force or the force exerted by the machine?
That depends on whether the machine is designed to multiply force or distance. A machine designed to multiply distance will exert less force than was applied, and a machine designed to multiply force will exert the greater force over a shorter distance than force was applied to it. As for work, output work is always less than input work because some energy is lost in overcoming friction.
