Weight and stretching

A force is a push or pull.

The weight of a body is the force of gravity on it.

The weight of a body is the same all over the earth.

Unit of force is the [blank_start]newton[blank_end]. It is denoted by the letter [blank_start]N[blank_end].

On most of the Earth's surfacee, the weight of a body of mass 1 kg is [blank_start]9.8 N[blank_end].

According to Hooke's law, [blank_start]extension[blank_end] is proportional to [blank_start]stretching force[blank_end].

According to Hooke's law, F = [blank_start]kx[blank_end].

On force-extension graphs, you should label each [blank_start]axis[blank_end] of your graph with the name of the [blank_start]quanitity[blank_end] or its symbol followed by [blank_start]/[blank_end] and the [blank_start]unit[blank_end].

The force constant of a spring is denoted by the letter [blank_start]k[blank_end] and the the extension of the spring is denoted by the letter [blank_start]x[blank_end].
