Answer 1

Answer:

c) a force is acted on the object and it is displaced

Answer 2

Answer:

When a force acts on an object over a distance, it is said to have done work on ... Kinetic energy – and all forms of energy – have units of joules (J). ... (1.b) Since the box is displaced 5 meters and the force is 2 N, we multiply the two ... ∫t1t2F⋅dx=∫t1t2Fdcosθdx=Fdcosθ ∫ t 2 t 1 F ⋅ dx = ∫ t 2 t 1 Fd c o s θ dx = Fd c o s θ ...
