FA = (0.205kg x 9.8) - (.0693kg x 9.8) = 2.01 - .679 FA = 1.33 N Conclusion: Since the distance of FB is greater than that of FA‚ the torque of FB is larger. The line of FA‚ lies directing on the 0.2 m axis‚ causing a torque of zero for FA. The theoretical and experimental values for both forces are very close‚ supporting the theory of torque and parallel

Lab II‚ Problem 3: Projectile Motion and Velocity Oct. 06‚ 2013 Physics 1301W‚ Professor: Hanany‚ TA: Vladimir Abstract A ball is tossed obliquely. The vectors of position and velocity are measured. The acceleration is calculated. Introduction A toy company is now making an instructional videotape on how to predict the position. Therefore‚ in order to make the prediction accurate‚ how the horizontal and vertical components of a ball’s position as it flies through the air should

Physics Lab Report#3 “Determining the period of a pendulum” Name: Fei Huo Date performed: October 1st‚ 2014 Period 5 Teacher: Mr. Glasel Purpose: The Purpose of this Lab was so that my classmates and I can examine what kind of factors affect the period of a pendulum. Introduction: In a simple form‚ the pendulum is a weight hung from a long string that Galileo discovered that it can be used to track the passage of time very accurately around 400 years ago. In this

The first slinky’s mass was weighed‚ using a scale‚ and its tension was measured using a force measurer 2. The slinky was stretched to 4m. 3. The linear mass density was solved for‚ by dividing the mass by the length. 4. The theoretical velocity was solved for‚ using the equation

Physics lab:9 Equilibrium of parallel force 11/09/2012 By: Camilo Salazar Jillian Ellis Purpose: To understand the conditions need for a rigid body to be in equilibrium when there are forces acting on the body from different sides. Theory: When force is applied on a rigid body for example a ruler it can either be in equilibrium or it can be unbalance. When the force is unbalance what would happen is this motion the body can be either translational or rotational. “A body in translational

Kathryn Marchessault Physics Lab LR Tuesday 8-9:55 Due 02/26/15 Experiment #1 Free Fall Experiment Abstract In this experiment we studied the motion of an object in free fall‚ that is an object being dropped from a certain height to Earth’s surface. In this experiment we tested the idea that no matter what the size‚ shape‚ color‚ etc. of the object if it would still experience the same constant acceleration throughout its fall (short distance). The constant downward acceleration it experiences
