M2.2 Forces

Front

What is the equation that links gravitational field strength, mass and weight?

Back

weight = mass x gravitational field strength

Front

Equation linking distance, force, and work done?

Back

work done = force x distance

Front

Equation linking extension, force applied to a spring, and spring constant?

Back

force applied to a spring = spring constant x extension

Front

Equation linking distance, time, and velocity?

Back

velocity = distance ÷ time

Front

Equation linking acceleration, change in velocity, and time?

Back

acceleration = change in velocity ÷ time

Front

What is the equation that links acceleration, mass, and resultant force?

Back

resultant force = mass x acceleration

Front

What is the equation that links mass, momentum, and velocity?

Back

momentum = mass x velocity

Front
