When you jump off a boat and the boat moves backward, this is an example of which law?
Newton's First law
Newton's Second law
Newton's Third law
Law of Universal Gravitation
Which of the following best illustrates Newton's Second Law?
A cup sitting on a table
A car accelerating when the gas pedal is pressed
Pushing a wall that does not move
Earth orbiting the Sun
What force keeps a book at rest on a table?
Applied force
Friction
Gravity
Normal force
When a rocket launches by expelling gas downward, which Newton's law is at play?
Newton's First law
Newton's Second law
Newton's Third law
None of the above
Why does a car require more force to move than a bicycle?
Due to its larger size
Because it has more mass
Because it is more aerodynamic
Due to its design
Which of the following best describes Newton's First Law of Motion?
Newton's First Law of Motion states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity, unless acted upon by a net external force. This law is also known as the law of inertia, implying that without an external force, the motion of an object does not change.
What is the formula associated with Newton's Second Law of Motion?
The formula associated with Newton's Second Law of Motion is F = ma , where \( F \) is the net force acting on an object, m is the mass of the object, and a is the acceleration of the object. This indicates that the acceleration is directly proportional to the force and inversely proportional to the mass.
According to Newton's Third Law of Motion, when you push against a wall, the wall pushes back with a force that is:
According to Newton's Third Law of Motion, when you push against a wall, the wall pushes back with a force that is equal in magnitude and opposite in direction to the force you applied. This principle shows that forces always come in pairs.
If a soccer ball is kicked and starts to move, which law explains why it eventually stops?
The soccer ball eventually stops due to Newton's First Law of Motion, which states that an object in motion stays in motion unless acted upon by an external force. The external forces of friction and air resistance cause the ball to slow down and stop.
Which example illustrates Newton's First Law of Motion?
A book remaining on a table illustrates Newton's First Law of Motion. The book stays at rest because no net external force is acting on it to change its state of motion.
