Work is done when a force is applied to an object moves that object. the work is calculated by multiplying the force by the amount of movement of an object
According to Newton (2nd law), Force = (mass) x (acceleration)
Substitute what we know : Force = (1,000 kg) x (3 m/s²)
Do the arithmetic: Force = 3,000 kg-m/s² = 3,000 newtons
