A bike rider is riding along the sidewalk and hit a tree stump which caused him to fall. Use the image below to write a ACE (Answer, Cite, Explain) to the following question.
Is this scenario an example of Newton's first law?
A man is riding a bike, and he runs into a small box on the ground. Falling forwards towards the ground
Answer: This example (does/does not) support Newton's first law.
Cite: (use what your remember from your lessons to provide your evidence) Ex: In class, I learned that
Explain: (How does your evidence support your answer?) This evidence supports that Newton's first law (is/is not) supported because
the bike rider was in motion and continued moving forward until an external force, in this case the tree stump, caused him to fall. This demonstrates Newton's first law, also known as the law of inertia, which states that an object in motion will remain in motion unless acted upon by an external force.
What is Newtons First Law?
Newton's first law, also known as the law of inertia, states that an object at rest will remain at rest, and an object in motion will continue moving at a constant velocity in a straight line, unless acted upon by an external force. In simpler terms, it means that objects tend to keep doing what they were already doing unless something else happens to them.
What example best represents velocity.
A: A plane traveling west at 60 kilometers per hour
B: A dog running 15 miles per hour on the grass
C: A bowling ball rolling down the lane at 2 meters per second
D: A bowl being pushed across the counter at 3 meters per second
Answer: The example that best represents velocity is A: A plane traveling west at 60 kilometers per hour.
Cite: In physics, velocity is defined as the speed of an object in a given direction. It is a vector quantity that takes into account both the magnitude (speed) and direction of motion.
Explain: In the given options, option A clearly states that a plane is traveling west at 60 kilometers per hour. This description includes both the speed (60 kilometers per hour) and the direction (west) in which the plane is moving. Therefore, option A best represents velocity as it satisfies the definition of velocity as a vector quantity.
