Questions and Answers
1.
Which of the following is an example of a Distance Force?
A.
Holding a book in your hand.
B.
A boy riding a bike.
C.
Gravity from the earth pulling you down.
D.
A car pulling a trailer.
Correct Answer C. Gravity from the earth pulling you down.
Explanation Gravity is an example of a distance force because it acts on objects regardless of their physical contact. It is the force that pulls objects towards the center of the Earth, even when they are not in direct contact with it. In the given options, holding a book in your hand, a boy riding a bike, and a car pulling a trailer are all examples of contact forces, as they require physical contact between objects. Therefore, the correct answer is gravity from the Earth pulling you down.

A Net Force is a force between two objects that are touching one another.
A.
True
B.
False
Correct Answer B. False
Explanation The given statement is false. A net force is not a force between two objects that are touching one another. Instead, it is the overall force acting on an object, taking into account all the individual forces acting on it. These individual forces can be contact forces or non-contact forces, and they can act on different objects. Therefore, the net force is not limited to forces between touching objects.

Which is the first law out of the three of Newton's laws?
A.
Any object at rest will stay at rest, unless it's acted upon by an unbalanced force. Any object in motion will continue to stay in motion unless it's acted upon by and unbalanced force. This law is often called the law of inertia.
B.
Every action has and equal opposite re-action.
C.
Acceleration may be produced when force acts on a mass. The bigger the mass, the greater the force needed to act on it.
Correct Answer A. Any object at rest will stay at rest, unless it's acted upon by an unbalanced force. Any object in motion will continue to stay in motion unless it's acted upon by and unbalanced force. This law is often called the law of inertia.
Explanation The first law of Newton's laws, also known as the law of inertia, states that any object at rest will stay at rest unless acted upon by an unbalanced force, and any object in motion will continue to stay in motion unless acted upon by an unbalanced force. This law describes the tendency of objects to resist changes in their state of motion, either staying at rest or maintaining their velocity. It highlights the concept of inertia, which is the property of matter to resist changes in motion.

Where does the time (independent variable) go when graphing speed?
A.
Y axis
B.
The line graphing the objects data.
C.
None
D.
X axis
Correct Answer D. X axis
Explanation When graphing speed, the time (independent variable) is plotted on the X axis. The X axis represents the horizontal axis of the graph and is used to measure and display the independent variable, which in this case is time. By plotting time on the X axis, we can observe how the speed of an object changes over a specific period of time.

To calculate speed, you take the _______ and _____ it by the ______.
Type in the letter next to the word, example: c. cat, b. elephant, a. giraffe The __c.___ meowed at the dog.
Correct Answer a. distance b. time c. divide
Explanation To calculate speed, you take the distance and divide it by the time.

My rate would be 2.89 miles an hour if my distance was 3.33 miles and my time was 1hr 15 min.
A.
True
B.
False
Correct Answer A. True
Explanation The given statement is true. To calculate the rate, we divide the distance (3.33 miles) by the time (1 hour and 15 minutes, which is equivalent to 1.25 hours). Dividing 3.33 miles by 1.25 hours gives us a rate of approximately 2.89 miles per hour, which matches the given statement. Therefore, the answer is true.

A ______ Force is where you take the _____ of all the forces acting upon one object.
Correct Answer b. Net a. sum
Explanation In physics, the term "Net Force" refers to the overall or resultant force acting on an object. It is determined by calculating the sum of all the individual forces acting on the object. Therefore, the correct answer is b. Net and a. sum.
