Impulse is a useful concept because it quantifies the effect of a force. A very large force acting for a short time can have a great effect on the momentum of an object, such as the force of a racket hitting a tennis ball.
In this experiment, you need to perform an integral over your force data to calculate the impulse. Capstone performs a summation algorithm to calculate the area under a curve. You can do this same technique using Excel. The impulse is the area under the force-versus-time curve. Like any integral, it can be approximated using a Riemann sum ...
The force applied by the spring is measured by a Dual-Range Force Sensor. The cart velocity throughout the motion is measured with a Motion Encoder. You will then use data-collection software to find the impulse to test the impulse-momentum theorem.
To calculate the impulse using Equation 9.3, we need to know the force function F (t), which we often don’t. However, a result from calculus is useful here: Recall that the average value of a function over some interval is calculated by. f (x) ave = 1 Δ x ∫ x i x f f (x) d x. where Δ x = x f − x i.
Physics. Core Practical 9: Investigating Impulse. Aims of the Experiment. To determine the change in momentum of a trolley due to a force acting on it. This is known as the impulse. Variables. Independent variable = accelerating mass, m. Dependent variable = time taken to pass between two light gates, t. Control variables.

Momentum And Impulse. In this lab, students use a motion sensor, force sensor, and dynamics system to investigate the relationship between the change in momentum of a cart undergoing a collision and the impulse imparted to the cart to change its momentum, and then use their data to establish a measurement-based relationship between change in ...
