newton’s laws test

newton’s first law

an object at rest/motion will stay at rest/motion unless acted upon by an unbalanced force

ex : a soccer ball resting on the grass will not move until someone kicks it, applying an unbalanced force

newton’s second law

f = ma

ex : the cart has a low mass. pushing it with a normal force causes it to accelerate quickly. however, a higher mass and the same force will lead to a slowed acceleration

newton’s third law

every action has an equal and opposite reaction

ex : pushing a wall and it pushes you back in the opposite direction

inertia

an objects tendency to resist a change in motion
