Objectives and Learning Targets. Define and calculate the momentum of an object.. Determine the impulse given to an object.. Lots of fun!. Win . valuable prizes!. 1.The reason padded dashboards are used in cars is that they . look nice and feel good. . decrease the impulse in a collision. . increase the force of impact in a collision. . . In classical mechanics, the momentum of a particle is defined as a product of its mass and its velocity, . . In an isolated system of particles, with no net force acting on the system, the total momentum of the system remains the same. However , we can see from a simple though experiment that the quantity . We will now quantify exactly how it hits the fan.. Momentum. Momentum = product of mass X velocity. Symbol for momentum is “p” (don’t ask me why). So, p = . mv.

Will the truck always have more inertia than the roller skate? . Will it always have more momentum than the roller skate?. Warm-Up. Estimate the amount of work the engine performed on a 1200-kg car as it accelerated at 1.2 m/s. Movement around a fixed point or axis. Spin; somersault . Occurs when a force is applied outside the centre of mass. An off centre force is referred to as an eccentric force.. Examples of a force being applied outside the centre of mass of an object or body to cause rotation. . Momentum. – tendency of objects to keep going in the same direction with the same speed. Depends on mass and velocity. Has direction. The momentum of a ball depends on its mass and velocity. Ball B has more momentum than ball A. Momentum = Mass x Velocity. p. =. mv. The SI unit for momentum is . kg·m. /s. Momentum and velocity are in the same . direction. Is a vector. Using the equation. p=. mv. At the same velocity, as mass increases – momentum increases. Momentum. – tendency of objects to keep going in the same direction with the same speed. Depends on mass and velocity. Has direction. The momentum of a ball depends on its mass and velocity. Ball B has more momentum than ball A. Momentum. Measures how hard it is to stop a moving object.. Momentum can be defined as . "mass in motion.". . All objects have mass; so if an object is moving, then it has momentum - it has its mass in motion. .
