FLASHCARD QUESTION
Front
What is Newton's First Law of Motion?
Back
Newton's First Law of Motion, also known as the Law of Inertia, states that an object at rest will remain at rest, and an object in motion will continue in motion with the same speed and in the same direction unless acted upon by a net external force.

FLASHCARD QUESTION
Front
What does Newton's Second Law of Motion state?
Back
Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This is often expressed with the formula F = m*a, where F is force, m is mass, and a is acceleration.

FLASHCARD QUESTION
Front
What is an example of Newton's First Law of Motion?
Back
A classic example of Newton's First Law is a soccer ball that remains at rest until a player kicks it. Once kicked, it will continue to roll until friction or another force stops it.

FLASHCARD QUESTION
Front
What is an example of Newton's Second Law of Motion?
Back
If you push a shopping cart, the acceleration of the cart depends on how hard you push (the force) and how heavy the cart is (the mass). A heavier cart requires more force to accelerate.

FLASHCARD QUESTION
Front
What is Newton's Third Law of Motion?
Back
Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction. This means that forces always occur in pairs.

FLASHCARD QUESTION
Front
Can you give an example of Newton's Third Law of Motion?
Back
When you jump off a small boat into the water, you push the boat backward as you move forward. The action of you jumping forward results in the reaction of the boat moving backward.

FLASHCARD QUESTION
Front
What is inertia?
Back
Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object; the greater the mass, the greater the inertia.
