I can explain what the equation F = m × a means and use it to carry out calculations.
Show transcript
Resultant force = mass × acceleration, F = m × a.
An object that is thrown in the air experiences a constant gravitational force towards the centre of the Earth.
An object that is thrown in the air is constantly accelerating towards the centre of the Earth.
Inertial mass is a measure of how hard it is to change the velocity of an object.
Inertial mass = force ÷ acceleration, m = F ÷ a.
