Moments _ GCSE Physics

The video tutorial explains the concept of moments, calculated by multiplying force by the perpendicular distance from the pivot. It provides examples, such as using a spanner, to demonstrate moment calculation. The tutorial also covers non-perpendicular forces, force multipliers, and balanced moments, using a wheelbarrow as an example. It concludes with an example of balanced moments, illustrating how small forces at greater distances can achieve larger forces.

What is the moment produced when a force of 15 newtons is applied at a perpendicular distance of 0.1 meters from the pivot?

• 1.5 Newton-meters

• 1.0 Newton-meters

• 2.0 Newton-meters

• 0.5 Newton-meters

How can you maximize the moment produced by a force?

• Apply the force at an angle of 90 degrees

• Apply the force at an angle of 45 degrees

• Increase the length of the lever

• Decrease the force applied

Why are moments often referred to as force multipliers?

• They increase the force needed to perform tasks

• They reduce the force needed to perform tasks

• They change the direction of the force

• They eliminate the need for a pivot

What is an example of a lever that reduces effort?

• A wheelbarrow

• A screw

• A door hinge

• A pulley

In a balanced system, if a force of 300 newtons is applied 2 meters from the pivot, where should a 700 newton force be applied on the opposite side to maintain balance?

• 1.5 meters from the pivot

• 0.86 meters from the pivot

• 1.0 meters from the pivot

• 0.5 meters from the pivot
