Theory: 3 Kinematic Measurement of Speed In this experiment the steel ball was moving in two dimensions both horizontally and vertically. Since these two components of motion are independent of one another, two sets of equations are used- one for the balls horizontal motion and one for its vertical motion. For the horizontal component, there are no external forces acting on the ball. Therefore there is no acceleration and the ball moves at a constant velocity. The distance the ball travels in the horizontal direction can be calculated using .
IBDP Physics Practice Lab - Factors Affecting the Drop Time of a Falling Body By Clevis Tam Aim: To investigate how the relationship of the terminal velocity of a falling parachute depends on the mass of the clay. Variables: • Independent Variables: The mass of the Clay (g) • Dependent Variables: The time the clay takes to reach the ground (s), The speed of the clay that is processed after collecting data (ms -1) • Controlled Variables: Method of releasing the clay, the area of the parachute Materials / Apparatus: 1. Meter Ruler (0-1m, measures to 0.001m) 2. Electronic Stopwatch (measures to 0.01s) 3. Drop Height (2.56m) 4.
After ejection, the WP-saturated felt wedges in the payload fall to the ground in an elliptical pattern. Each wedge then becomes a point or source of smoke. The M825 is ballistically similar to the M483A1 (DPICM) family of projectiles. Employment. Smoke is employed by using the quick smoke and immediate smoke techniques.
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”?
Next, using the equations the total distance the ball would travel was found. After that, the students called over Mr. Neenan so that he could observe the firing of the projectile launcher. The projectile launcher was at the end of the table and the calculated distance was marked off on the floor by a target. The projectile launcher was then set up perfectly horizontal and fired. Part Two: This part of the lab was to hit Mr. Bill with the projectile as he was sitting on the floor.
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
FREE FALL ACCELERATION Section : 03 Name & Surname : Partner’s Name : Instructor’s Name : Experiment Date : Submission Date : ABSTRACT In this experiment our aim was to examine the relationship between height and how long it takes the sphere to reach the ground after being dropped from rest. We used a falling sphere apparatus, a release unit, a meter scale, a digital timer and graph papers. We measured falling time of the sphere dropped from rest at 5 different heights. The measurements showed that as the height decreases, time for the sphere to reach the tray decreases too. THEORY Every object near the surface of the Earth is subject to a gravitational force which is toward the center of the Earth.
As the vibrating string moves in the forward direction, it begins to push upon surrounding air molecules, moving them to the right towards their nearest neighbor. This causes the air molecules to the right of the string to be compressed into a small region of space. As the vibrating string moves in the reverse direction (leftward), it lowers the pressure of the air immediately to its right, thus causing air molecules to move back leftward. The lower pressure to the right of the string causes air molecules in that region immediately to the right of the string to expand into a large region of space. 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.
Newton’s Second Law and the Work-Kinetic Energy Theorem October 13, 2010 Abstract This experiment utilizes an air track first as an inclined plane with the slider accelerating due to gravity and second as a level surface with the slider accelerating due to the pull of an attached free-falling object of known mass. In both cases, the Work performed is calculated based on formulas for mechanical work and for kinetic energy. The two results are compared. The first part yielded an average acceleration of 0.715 m/s2 (a 1.58% error) and the average result for the Work performed was 0.0204 N*m with only a 0.9% difference. The second part suffered critical errors due to improper data and the results are not significant or useful.
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.
