there was more force applied; therefore, there was more movement.

There was less force applied; therefore, there was less movement.

Explanation:

As we know that work done is given by the formula

so here we need to find the product of force and displacement

now here we know that if applied force will be less than it will give less displacement to the object as we know that acceleration depends on the applied force as the relation below

also the distance moved of the object will depends on the applied force as the relation below

so if we apply less force then it will have less acceleration which will cause less distance moved by the object.

so from above formula the work done will be less
