of a puck constrained by a string‚ traveling a circular path on an air table. Be sure the Gizmo has these settings: radius 8 m‚ mass 5 kg‚ and velocity 8 m/s. Then click Play and observe the motion of the puck. a. The puck in the Gizmo is traveling at a constant speed‚ but it is NOT traveling at a constant velocity. Explain why. b. Because the velocity of the puck is changing (because its direction is changing)‚ the puck must be experiencing an acceleration. Click BAR CHART and choose Acceleration

was to analyze the motion of a student walking along a straight line in front of the motion detector moving back and forward with different speed trying to match the graph provided. To also understand and interpret graphs of distance vs time and velocity vs time. To also know what the slopes of the each graph represent which tells how far the student travelled‚ the speed and whether the motion of the student is accelerating or decelerating. THEORY: The particle position X is the with respect

temperature‚ angle‚ area‚ speed‚ distance‚ volume and density are examples of scalar quantities. * Vector Quantities: Quantities that require both magnitudes and direction to specify them are called vector quantities or vectors. Displacement‚ velocity‚ force‚ momentum‚ weight etc. are the examples of vectors. Q5: A farmer moves along the boundary of a square field of side 10 m in 40 s. What will be the magnitude of displacement of the farmer at the end of 2 minutes 20 seconds? Answer: As

positioned underneath a table recorded the golf ball’s pattern of motion‚ when dropped. The main objective of performing this experiment is to measure the velocity and position of the ball to eventually find the acceleration of free fall. A computer program called‚ DataStudio‚ was used to create a graph of position vs. time and a graph of velocity vs. time. The second part of the experiment involved randomly dropping a ruler and having your partner catch it to determine reaction time. Questions

cart with a spring. A stiff spring will be used. We will collect the information through two items. We will use distance and time as information collectors. This will measure the acceleration‚ velocity‚ and position of the cart as it moves down the track. The most important measurement collected is the velocity; which will be used to calculate the momentum. We will also explore how mass impacts in the change of momentum‚ and if there can be a non-changing impulse between the two carts with different

I knew my acceleration for Y was -9.8‚ the velocity initial for Y was zero‚ and the time it will take for the ice cream to reach zero is .452. For X I know that time is also .452‚ and that the acceleration is zero. To get started I decided the vertical distance‚ and then I calculated the time‚ using the time I figured out the initial velocity‚ and then I used this to figure out the distance the cone would go in the X direction. Then using the
