Test Question: Q30
Original Answer: 5 **INCORRECT**
Original Reasoning: I read the graph incorrectly. I ignored the fact that sled is actually increasing its speed. I thought because it was in the fourth quadrant, that the sled would be slowing down because it is negative.
New Answer: 2
New Reasoning: The direction is not specified in the graph, but I can tell the sled's speed is increasing because the force applied on the sled is constant, therefore the sled is increasing its speed at a constant acceleration.

Test Question: Q27
Original Answer Choice: 3 **INCORRECT**
Original Reasoning: When reading this situation, I believed that in order for the truck to be pushed by the car, the car would have to exert a greater force on the truck.
New Answer Choice: 1
New Reasoning: In this situation I ignored Newton's third law.

Test Question: Q26
Original Answer Choice: 3 **INCORRECT**
Original Reasoning: I thought that in order for the truck to be moved by the car, the car would need to be exerting a greater force on the truck than the truck was exerting on the car.
New Answer choice: 1
New Reasoning: When concluding this situation, I forgot about Newton's third law which states that every object applying a force has an equal and opposite force by the object it is interatcing with.

Test Question: Q4
Original Answer Choice: 4 **INCORRECT**
Original Reasoning: I thought that in order for the box to move the force exerted by the person on the box would need to be greater than the force the surface area exerts on the box.
New Answer Choice: 3
New Reasoning: I agree with Dillon. There are no unbalanced forces in this problem. When drawing a motion diagram, there is no acceleration because it is moving at a constant speed, therefore the arrow of the person on the box must be equal to the arrow of the surface area on the box.

Test Question: Q21
Original answer: 1 **INCORRECT**
Original Reasoning: When I was reading this situation, I saw "massive truck" which made me think that because the truck has the greater mass it will exert a greater force.
New answer: 5
New Reasoning: Newton's third law.

Test Question: 20
Original Answer choice: 1 **INCORRECT**
Original Reasoning: I thought that the force of teh truck would exert a greater amount of force on the car than the car exerts on the truck because the truck has a greater mass so when the collide the truck would apply a greater force on the car.
New Answer Choice: 5
New Reasoning: Newton's thrid law. The force of an object on another object is equal to the other object on the original object. The truck exerts the same amount of force on the car as the car exerts on the truck.

Test question: 8
Original answer choice: 2 **INCORRECT**
Original Reasoning: I originally thought that the downward force was increasing because it was falling, but I was incorrect.
New Choice: 1
New Reasoning: The downward force of the coin is the force of the Earth on the coin. This force is constant no matter the situation. The force the Earth applies on an object is a constant to that object, therefore the unbalabced force downward has to be constant.

Test Question: 7
Original Answer choice: 4 **INCORRECT**
Original reasoning: I initially made the same mistake as Joe. I thought that there would be an unbalanced force of 0 because I thought the coin was in equilibrium and would stop for a moment at the top
New answer: 1
New reasoning: It is 1 because the unbalanced force is down and constant. The downward force does not change.

Test Question: 6
Original Answer choice: [7] the unbalanced force is up and decreasing. **INCORRECT**
Original Reasoning: I thought that the force of the coin being released was greater than the force of the downward pull of the Earth on the coin, so the coin was going upward but slowing down.
New answer choice: 1
New Reasoning: I was incorrect because the unbalanced force is down and constant. Eventhough the coin is moving upward, the unbalanced force will be down and constant. The downward force is the force of the Earth on the coin and that force does not alter.

Re: Dynamics Test: Q5

liz frino — Sat, 02 Jan 2010 10:13:52 -0000

My original answer was 4. I thought that if no objecting is interfering with the box, the box would continue moving at a constant velocity. But now after viewing the problem again I realize that with no force being exerted on the box, the box will start slowing immediately and continue until he stops, therefore, the answer would be 3.

Test question: Q1
Original answer choice: 3 **INCORRECT**
original reasoning: Originally I made a mistake in thinking that the book was excerting a downward force on the table
New answer choice: 2
new reasoning: There is no downward force exerted from the book, the force with a downward pull is the Earth on the book.

best story everrrrr!! hahahahaha i had no idea that was a law, honestly i think me and my friends have worn masks in CVS hahaha luckily we didnt get caught though. one time when i was about 14 me and my friends were having a sleep over, some girls went out to swim at like 5 in the morning and the cops showed up haha another time with the same people cops caught us at like one thirty am coming out of a park and we got tickets for being out to late and driving with too many people. if only they knew that five minutes before that we were on the swing sets acting like six year olds not delinquents! haha

HAPPY EASTER!!
not suprising, this was another one of your fantastic stories :) it reminded me of when i was younger, i was always atheletic but nothing really spectacular, but some how my dad managed to get me onto every serious team, such as traveling soccer, traveling soft ball, and even all stars for soft ball (my team made it to states but i was on a cruise haha). i remember playing basketball, which i hated, and my dad asked if i wanted to play traveling. i was like NOOOO!! hahah Ironically, now i dance competitively and play tennis hahahahahahaha
