Activity no. 1.2: Inertia Tricks
Materials: Coin, Paper, and small cup/glass
Procedure:
1. Place the paper on the small cup/glass.
2. Place the coin on the paper.
3. Pull the paper quickly. Observe.
Think about it:
1. What happened to the coin as you pull the paper?
2.Why do you think the coin does not move with the card?
1. Place two coins on the edge of the table at the same distance above the floor.
2. Drop the two coins at the same time and listen to the sound as they strike the
floor. Coin A must be dropped directly while
Coin B must be thrown in a projectile. You can
do this by flicking the coin across the table to
strike the first coin at the table’s edge. Try to
aim “off center”, this will drop the coin straight
down while projecting the coin with some
horizontals peed.
3. Record the time it takes for the two coins to
drop the floor. You may ask assistance of two
person in your house or someone to record the time.
Record your data on the provided answer sheet.
Calculate the time it will take for the coin to drop using equations for free-falling
bodies and projectile motion. Assume a zero initial velocity for both coins.
Compute for the percentage difference between calculated time and the experiments.
Show your solutions on the provided answer sheet.
Fill in the blanks. Write your answers on the provided answer sheet.
An object travelling in a curved path is called_____.The motion is called_____.The Path it travels is called_____.When an object is thrown and follows this motion,the vertical component of it's acceleration is equal to_____ while the horizontal component of its acceleration is equal to_____.This is due to the fact that the horizontal component of its velocity is always_____ while its vertical component is_____. The vertical component of velocity_____ when it goes upward. It becomes____ when it reaches the peak. Upon returning to the ground, the velocity_____ and directed_____.
A viral video of a Physics professor in Silliman University is currently circulating because of his demonstration on circular motion. He securely tied the handle of a pail through a string. Then, he filled it with water. He reminded the students that he will swirl the system of objects and assured they will not get wet. Everyone was screaming and when he was finished, the class was shocked no amount of water was spilled throughout the demonstration. Why do you think this happened? Write your answer on the provided answer sheet.
Emmanuel Zacchini launched as a human cannonball in 1940 soared over three Ferris wheels each 18.0 m high covering a horizontal distance of 10.63m. a.) Assuming that the point of projection is 2.50 m above the ground and that he landed safely on a net placed at the same level, find his initial velocity. b.) Assuming that he missed the net and landed on the ground, with what velocity will he strike the ground?
. A girl delivering newspapers covers her route by traveling 3.00
blocks west, 4.00 blocks north, and then 6.00 blocks east. (a)
What is her resultant displacement? (b) What is the total
distance she travels?
The force is at its minimum when the angle is 90°c and the particle moves in a circle.
A. True
B. False
Magnetic field exists in a region of space if a moving charge there experiences a force due to its motion.
A. True
B. False
The young modulus of elasticity is defined as
E=f/a÷e/l
obtain the dimension of E where f=force
A=area
e and l =length
