SPH4U0 2-D COLLISIONS LAB PURPOSE To determine if momentum and kinetic energy are conserved during elastic and inelastic collisions. PROCEDURE AND CALCULATIONS 1. Run both the elastic and inelastic collision simulations and record the data as instructed by the teacher (you will do an import). You will need to base your calculations on the data before and after the collision. Do not use data in the middle because it is not clear exactly when the collision occurs. The software measures time

Collisions Inelastic Collisions Elastic Collisions Stationary Target Moving Target Collisions in 2-Dimensions (Glancing Collisions) Inelastic Collisions Collisions in which kinetic energy is not conserved. Initial kinetic energy is transformed into other types of energy (thermal‚ potential etc.) Total final kinetic energy is less than the total initial kinetic energy. If two objects stick together as a result of the collision‚ the collisions is inelastic. Even though the

the ball. During this collision‚ there is an impulse. This is the force multiplied by the length that this force is applied. Impulse = 10‚000N multiplied by 0.0005s / 0.046kg = 108.69 This would mean that the ball is moving

Still objects have no kinetic energy. Hint: Energy variables are capital Momentum proportional to mass and velocity p=mv Units= kg time m/s And is vector in as direction as velocity Conservation laws are applied in closed systems only Collisions are closed Momentum is conserved/////

Find (a) the combined final speed if they stick together. (b) if the collision is perfectly elastic‚ their individual speeds if the pucks do not stick together. 2. A bullet of mass 10 g has a muzzle velocity of 300 m/s. Find (a) the momentum of the bullet (b) the recoil velocity of the gun if its mass is

exhibits various concepts related to physics including friction‚ collisions‚ conservation of energy‚ and conservation of momentum. Momentum is force of moving objects. It can be measured by multiplying an object’s mass and velocity. Basically‚ the concept of conservation of momentum is that the total momentum of objects before a collision is equal to the total momentum of the objects after the collisionIt is essential to remember that momentum is a vector quantity‚ meaning its definition requires the

Use DataStudio to compare the change in momentum of the cart with the integral of the measured force vs time graph.

Physics 211 Experiment #9 Impulse – Momentum Experiment Discussion Impulse‚ momentum‚ and the impulse-momentum relationship are defined and discussed in the text. The momentum of an object with mass m and velocity [pic] is [pic]. The impulse of a resultant force from time t1 to time t2 is When the force is plotted versus time‚ the impulse is the area under the curve between t1 and t2. [pic] The impulse-momentum relationship states that if an object with mass m is acted on by a force

conservation of energy and momentum using projectile motion. Theory: The ballistic pendulum demonstrates both the constant horizontal velocity in projectile motion and the conservation of momentum. Because there is no acceleration in the horizontal direction‚ the horizontal component (v_x) of the projectile’s velocity remains unchanged from its initial value throughout the motion. In a closed isolated system‚ if no net external force acts on a system of particles‚ the total linear momentum of the system cannot
