You can use a hammer as a lever to remove nails, making a difficult task much easier.If the resistance arm is 5 cm long, calculate how long the effort arm would need to be to give you a mechanical advantage of 5.

The average force necessary to stop a hammer having momentum of25 N S , in 0.05 second is I) 5N II ) 50 N III ) 500N IV) 5000 N

hy do we prefer to use a wrench of longer arm?

Calculate the mechanical advantage of a hammer if the input force is 125 N and the output force is 2,000N.

A 1 kg hammer is taken to a distance of 2500 km from the Earth's surface.Using the graph, determine the size of the gravitational force it will experience.

Determine the missing words needed to complete the following sentences and enter them into the right-hand column.A force applied by a person to make something move is known as an _______________ force.effort Every lever has three components: an effort arm, a resistance arm and a _______________.A lever is balanced when: effort force x length of effort arm = resistance force x length of _______________ arm.A lever gives you a trade-off: increase the distance and you can use less _______________.
