If you're going in a specific direction, you will always go in that direction unless something happens to you. 2. “The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.” The second law shows that if you apply the same amount of force on two objects which have different masses, you will get different accelerations. The bigger the mass of an object, the less effect the force applied has on it.
This is because there is a relation between the energy of light and its frequency: the greater the energy the higher the frequency. As light travel upwards in the earth´s gravitational fields, it loses energy, and so its frequency goes down. To someone high up, it would appear that everything down below was taking longer to happen. A prediction tested, showed that the clock at the bottom, which was nearer the earth, was found to run slower, in exact agreement with general relativity. The difference in the speed of clocks at different heights is now of considerable practical importance’s, with the advent of very accurate navigation systems bases on signals from satellites (GPS).
The three laws of motion explain how an object will either stay in motion or what makes it move,Force= mass X acceleration, and action and reaction. This essay will basically take the dry basics of the rules and elaborate and give examples of how they work so you will have a better understanding of the laws. Including examples of labs that demonstrate, lets introduce the first law. Newton’s 1st law of motion states that an object at rest will stay at rest until acted on by larger force. Objects in motion will stay in motion until stopped by a larger force.
Because the length of a pendulum L, and the square of the period of the pendulum T2 are directly proportional, we were able to determine g by calculating the slope of the T2 vs L graph. From our calculations, this value turned out to be 10.3m/s2, while the accepted value for the acceleration is 9.8m/s2. Percentage Difference = 10.3−9.8 9.8 = 5.10 % There are a few reasons for the small error in our estimation: 1. There was some uncertainty in measuring the length of the pendulum L.
You can find the volume of a rectangular prism using the same formula given above (V= l × w × h.) Another way to say it is to multiply the area of the base times the height. 1. 2. 3. Find the area of the base for the rectangular prism pictured above.
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
Weighing scale * The clamp should be placed tightly on to the desk. * The Pole should be placed in one of the hole in the C-clamp * The right angled clamp should put on top of the pole * The spring screwed on to one of the jutting screws. * Tape the ruler to the pole as accurate as possible under the unextend spring. Lab set up Method: 1. Weigh each mass on a weighing scale and record on data table with uncertainty.
The more mass taken away, the quicker it will vibrate. Theory: Oscillation is a way of returning a system to its equilibrium position, the stable position where there is no net force acting on it. Once a system is thrown off balance, it does not return to is original state; it oscillates back and forth about the equilibrium position. The movement of an oscillating body is called harmonic motion. The oscillating motion of a spring is caused by the stretching or compression of it.
One person will be in charge of releasing the parachute, while the other would be recording data and timing how long the parachutes would take to hit the ground. 5. Counting 1,2,3, then releasing the parachute from the top of the drop point. 6. Three repeated trails for each mass (Step 5) 7.
Expansion, an increase in the volume of a substance, usually due to the addition of heat to the substance. The heat causes the molecules of the substance to move farther apart, making the substance occupy more space. A loss of heat causes the opposite effect, known as contraction. Although most substances expand when heated, not all expand at the same rate. Aluminum, for example, expands twice as much as iron when both are heated the same amount.
