Questions 1 - 1

Which of the following best illustrates Newton's Second Law?

If an object is not accelerating, then the net force on it is zero

A ball is rolled across a table and does not stop until it hits an area with friction

When two cymbals collide, some kinetic energy is converted into sound

As a hammer hits a nail, the nail also exerts a force on the hammer

Newton's Second Law is best represented as an equation, in which the product of mass and acceleration is equal to net force:

$F_{net}=ma$

By this principle, if there is zero acceleration, then the force must also be zero.

$F_{net}=m(0\frac{m}{s^2})=0N$

A non-zero acceleration must be present if there is a non-zero net force.
