A picture is hanging on a wall and does not move. The law related to the situation is
Newton's 1st Law
Newton's 2nd Law
Newton's 3rd Law
None of them
Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).This statement is related to
Newton's 1st Law
Newton's 2nd Law
Newton's 3rd Law
None of them
________________states that an object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Newton's 1st Law
Newton's 2nd Law
Newton's 3rd Law
Einstein's Law

Newton's 1st Law
Newton's 2nd Law
Newton's 3rd Law
