Abstract In this experiment Newton’s Second Law of Motion was measured with the use of the gravitational acceleration g on Earth by applying a free fall process. Objective The objective of this experiment is to validate Newton’s Second Law of motion. In experimenting the Law the measurement of acceleration of gravity was used by measuring the distance a dropped ball travels for a specific amount of time. Procedure First‚ measurements were taken of the distance from the stairway

Physics Investigation Investigation Question: Does the mass effect the acceleration of each person while going down the slide? Hypothesis: The heavie How will we take measurements? Using the equations: V= u+at s=ut + .5 at2 Measure the overall distance the mass will be travelling. To calculate the time it took to reach the end of the ramp‚ then using the equations above‚ add in the distance‚ time‚ and initial velocity. Variables Independent: Difference of weight on each

Centripetal force (from Latin centrum "center" and petere "to seek"[1]) is a force that makes a body follow a curved path: its direction is always orthogonal to the velocity of the body‚ toward the fixed point of the instantaneous center of curvature of the path. Centripetal force is generally the cause of circular motion. In simple terms‚ centripetal force is defined as a force which keeps a body moving with a uniform speed along a circular path and is directed along the radius towards the centre

CENTRIPETAL FORCE ON A PENDULUM OBJECTIVE To measure centripetal force exerted on a pendulum using the force sensor bob and in so doing compare this value determined by force calculations based on the height of the pendulum. THEORY Newton’s laws of motion are the basis for this experiment. Newton’s first law of motion states that a body in motion will remain in motion unless acted upon by an external force. Newton’s second law of motion states that the rate of momentum of a body is dependent on

The average acceleration‚ a = ᐃv/ ᐃt‚ is in the same direction as ᐃv‚ that is‚ toward the center of the circle. As the object moves around the circle‚ the direction of the acceleration vector changes‚ but its length remains the same.One should take note of the fact that the acceleration vector of an object in uniform circular motion always points in toward the center of the circle. Due to this fact‚ the acceleration of such an object is called center- seeking or centripetal acceleration. Remember

experience. The Earth’s radius is 6378 km. As a result of your increased distance from the centre of the Earth at the maximum point at the Earth’s radius on the equator‚ you have a lower centripetal force at that location. This is shown by the formula for centripetal acceleration‚ which is: [pic] Where centripetal

Speed is constant‚ velocity is not. Centripetal Acceleration‚ – acceleration that maintains the object along a circular path directed towards the center. Also called as radial acceleration. In 1673‚ Christian Huygens‚ determined the following relationships. Velocity‚ Where‚ r = radius of curvature/path‚ t = time/period. Frequency (f) – number of revolutions of cycle completed per unit time. So‚ Expressing centripetal acceleration in terms of frequency‚

1 Centripetal Acceleration Imagine a marble sitting on a rotating turntable. The different vectors representing velocity for the travelling marble are shown below. Notice that the size of the vector remains the same but the direction is constantly changing. Because the direction is changing‚ there is a ∆v and ∆v = vf - vi ‚ and since velocity is changing‚ circular motion must also be accelerated motion. vi ∆v vf -vi vf2 If the ∆t in-between initial velocity and final velocity
