The acceleration due to gravity from the acceleration of the ramp is 7.5m/s2. 7 trials were done to get the correct amount of error. The angle of 9° was found by dividing the 10cm of height of the ramp by the base of 105.5cm of the ramp. Sin θ = 10cm/105.5cm = .94 = 9°. The total acceleration of the cart was 1.172m/s2 because it was divided the total distance by the total time and multiplied by two a = 2(105.5cm/1.8s) = 117.2cm. 117.2 were converted into meters 1.172m/s2. Precision will matter because
Woah, That’s a MASSive Acceleration Emily Walters Patterson - Block 8 Section I: Purpose/Introduction Part A: Problem How does the acceleration of an object change when the mass of the object is increased? Part B: Objectives determine the relationship between cart mass and acceleration observe the effects of Newton’s First Law use Newton’s Second Law (F = m(a)) to calculate the force of gravity Part C: Background Acceleration (m/s/s) is any change in an object’s velocity. Velocity is
shapes that we expected to see in a position vs. time (inverted parabola), velocity vs. time (line with a negative slope), and acceleration vs. time (flat line) graph. We found our graphs and data to be exceptionally supportive of the physics concepts outlined in the pre-lab section of this report—at maximum height, the velocity of the ball was found to be 0 m/s and the acceleration (9.1 m/s2) was found to be close the standard value of g (9.8 m/s2). We also found the slope of the line for the velocity
experiments with falling bodies, from which he deduced the acceleration due to gravity and its independence of the body’s mass and discovered that projectiles follow parabolic paths. Examples of parabolic motion include the paths of a stone thrown into the air at an angle, a bullet shot from a gun and water sprayed from a hose. The basic fact here is that every object that falls freely under the action of the Earth’s gravity experiences an acceleration g that is directed vertically down. When an object
Purpose This lab was designed to determine what measure can be taken to protect a falling egg. Momentum and Newton's third law were used to create the best design for the fallen egg. Background This lab uses the components of momentum and Newton's third law. Momentum equals mass times velocity, this was an important measurement to take into account during the egg drop because it determines the amount of force that the object will have when it hits the ground. The less momentum it has the better
OBJECTIVE: The purpose of this experiment is to better understand forces and torques when an object is at static equilibrium. INTRODUCTION: In order for an object to be in static equilibrium, meaning at rest (zero acceleration and velocity), the sum of all external forces acting on that object along any axis must be zero. F ⃗net= ∑▒〖F ⃗_i=0〗→∑▒〖F_ix=0;〗 ∑▒〖F_iy=0;〗 ∑▒F_iz =0; [1] In addition, because the object is not rotating, the sum of all torques in any axis must be also be zero. τ ⃗_net=∑▒〖τ
determine the accelerations of all the moving parts in the assembly. Dynamic forces are proportional to acceleration, from Newton's second law. We need to know the dynamic forces in order to calculate the stresses in the components. The design engineer must ensure that the proposed mechanism or machine will not fail under its operating conditions. Thus the stresses in the materials must be kept well below allowable levels. To calculate the stresses, we need to know the static and dynamic forces on the parts
speed limits play a role in car collisions. Hypothesis Mass will change how quickly a car will be able to change its speed because of the amount of weight on the car. The increase of speed and mass will have an impact on the car because the amount of force and pressure applied onto the other car will be much greater, causing it to move back more. Background Research A collision is a process
Title: Force Plate Analysis of a Vertical Jump Introduction A vertical jump is a simple measure of lower limb power, it is defined as the highest point an athlete can reach from a standing jump. Performing a vertical jump requires balancing on the forefoot and at the same time pushing the body upward with high effort. It is a movement consisting of an interaction of the lower extremities by extension in mainly three joints and that is the hip, knees, ankles and involving the activity of large muscle
viewed as a projectile. A projectile is just any object that when anticipated or dropped, proceeds in movement by it inertia and is influenced just by the force of gravity. Additionally as mentioned before; by definition a projectile has a solitary force that follows up on it - the force of gravity. In the event that there were any other force following up on an object, then that object would not be a projectile. Despite whether a projectile is in motion downwards or upwards, upwards and rightwards
