(this is my sister on my acc I'm letting her) True or False? When you use a pulley you use less force to pull up a load.Explain your thinking below. btw im in grade four so no fancy words.

A pulley would help lighten the load that you are trying to pull up, which may make it easier for you to get the load to your designated area. The more complicated it is, usually the more 'lighter' it becomes, or the less force you have to exert.

For example, you will have to give a 100% energy in trying to life a heavy box. However, if you use a simple pulley (only one), you may only have to exert 75% more energy, for the weight is significantly lower.
