Example Question #1 : Newton's Second Law
Which of the following best illustrates Newton's Second Law?
Possible Answers:
A ball is rolled across a table and does not stop until it hits an area with friction
If an object is not accelerating, then the net force on it is zero
As a hammer hits a nail, the nail also exerts a force on the hammer
When two cymbals collide, some kinetic energy is converted into sound
Correct answer:
If an object is not accelerating, then the net force on it is zero
Explanation:
Newton's Second Law is best represented as an equation, in which the product of mass and acceleration is equal to net force:
By this principle, if there is zero acceleration, then the force must also be zero.
A non-zero acceleration must be present if there is a non-zero net force.
