What are momentum and impulse? (article) | Khan Academy

Impulse is a term that quantifies the overall effect of a force acting over time. It is conventionally given the symbol and expressed in Newton-seconds. For a constant force, . As we saw earlier, this is exactly equivalent to a change in momentum . This equivalence is known as the impulse-momentum theorem.

Thus, larger hip adduction would increase the HAM impulse by increasing the lever arm between the hip joint center and GRF vector. In muscle-driven gait simulations, an increase in hip adduction was shown to be the most influential kinematic affecting the increase in peak HAM and the hip contact force [ 18 ].

The physics of baseball - University of Texas at Austin

The physics of baseball. Baseball players know from experience that there is a ``sweet spot'' on a baseball bat, about 17cm from the end of the barrel, where the shock of impact with the ball, as felt by the hands, is minimized. In fact, if the ball strikes the bat exactly on the ``sweet spot'' then the hitter is almost unaware of the collision.

How Does A Mousetrap Work? | HST Physics Learning Center

In a second-class lever the effort force is at the other end, with the load in the middle. In a third-class lever, the load is at the end and the effort force is between the fulcrum and the load. When you set the mousetrap, you are using a second-class lever. The load is the arm of the spring that is being pushed down to compress the spring.
