We used a vernier caliper to obtain the diameter of those two and therefore, the radius. When adding all the numbers together, we found that the true radius(r) of the orbit was 0.139 m. To find our tension, we needed to find out how much weight we needed to pull the object towards away from the spring and on the tip of the pointer as shown below. The tension needed to pull the mass on the tip of the pointer 1.05 kg. In theory the force of acceleration needed to pull the mass to same exact spot should equal the force of tension multiplied by the force due to gravity. Using Newton’s second law, F=ma, we know that the
The back and forth vibration of the string causes individual air molecules (or a layer of air molecules) in the region immediately to the right of the string to continually vibrate back and forth horizontally. These back and forth vibrations are imparted to adjacent neighbors by particle-to-particle interaction. The result of such longitudinal vibrations is the creation of compressions and rarefactions within the air. Mechanical wave Sound is a wave that is created by vibrating objects and propagated through a medium from one location to another. The sound wave is transported from one location to another by means of particle-to-particle
The gravity equals Mass times Acceleration, or G=ma. However, extra Gravity can be artificially generated in any direction by sudden changes in the motion of airplane. For instance, when the airplane is taking off, you feel you are pushing back into your seat. This is because the velocity of the airplane changes and exerts acceleration (The Basics of Flight). Lift “How can a heavy metal lift off the ground”?
It consists of two major components--the projectile carrier and the payload. The projectile carrier delivers the payload to the target. The payload consists of 116 WP-saturated felt wedges. The smoke screen is produced when a predetermined fuze action causes ejection of the payload from the projectile. After ejection, the WP-saturated felt wedges in the payload fall to the ground in an elliptical pattern.
Description: In these series of experiments the apparatus we used was a spring gun that for the first experiment shot a steel ball freely which eventually struck the floor. For the second and third experiments the gun fired the steel ball into a pendulum. To measure the velocity of the steel ball, when it was launched freely, carbon paper and a 2-meter ruler were used to determine the distance it travelled and then kinematics were used to calculate the balls initial velocity. When the steel ball was launched into the pendulum the laws of conservation of energy and momentum were utilized to determine the balls initial velocity. Theory: 3 Kinematic Measurement of Speed In this experiment the steel ball was moving in two dimensions both horizontally and vertically.
Buoyancy is one principle that causes a hot air balloon to fly. It is an upward force that pushes things into the air. However, the weight of an object must be less than or equal to the buoyant force so that object will float. An object like a balloon, must weigh less than the air it displaces. In order to do so, the balloon has to be filled with air that is not as dense than the air around it.
Mass can also be defined as how much inertia something has. The second law of motion says: “A net force acting on an object causes
Because it was not a direct force like pushing or pulling. The force of gravity on an object depends on the mass and the distance. Free fall is caused by this gravitational force. Every object falls down at the same speed because the gravitational acceleration is independent of the mass of the object. Gravitational acceleration was found using this formula: g=2ht2 Impact speed of the falling objects was found using this formula: v=2ht Percentage error between calculated values and those obtained from the slope of the graphs were found using this formula: percent error=calculated value-slopecalculated value x100% PROCEDURE Firstly we placed the falling sphere apparatus on the table.
The actual speed of P and S seismic waves depends on the density and elastic properties of the rocks and soil through which they pass. In most earthquakes, the P waves are felt first. The effect is similar to a sonic boom that bumps and rattles windows. Some seconds later, the S waves arrive with their up-and-down and side-to-side motion, shaking the ground surface vertically and horizontally. This is the wave motion that is so damaging to structures.
