science forces and electricity

How is torque measured?

Torque is measured in Newton meters (Nm) and is calculated by multiplying the force by the length of the lever.

What is the formula for calculating torque?

Torque = force x length.

What are levers?

Levers are simple machines that make work easier by using a rigid rod that rotates around a point called a fulcrum.

What is a pivot?

A pivot is a fixed point from which an object rotates or turns.

What is weight?

Weight is the force of gravity acting on an object's mass.

What is mass?

Mass is how much matter is in an object.

What is friction?

Friction is a force that resists the relative motion between two objects in contact.

What is static electricity?

Static electricity is the buildup of electrical charge on the surface of an object, usually caused by friction.

What is electricity?

Electricity is a flow of charge around a circuit.

What is electron transfer?

Electron transfer is when electrons move from one object to another due to contact, rubbing, electron movement, and charge separation.
