2/3 AP: Momentum

Momentum is a conserved property of a system. This conservation can be demonstrated by using Newton’s third law (Fa/b = -Fb/a) to develop the equation: mΔva + mΔvb = 0 Momentum is given the lowercase p as its symbol. The change in momentum (Δp) of an object is defined as…Read More

1/28: AP Phys: Power

In our study of energy and work, we have yet to address the time it takes to transfer energy from one system to another. This rate is called power, and given symbol P (upper case, we’ll use the lower-case p for another variable later). Since the rate is time based,…Read More

1/23 AP Phys: Quantifying spring energy

Write the slope of your F/x calculations for each spring under the matching color on the whiteboard on the right. Spring constants As we saw yesterday, the relationship between the force applied to a spring and the stretch of the spring is linear. The slope of the F/ Δ x…Read More

1/22 AP Phys: Energy in springs: Hooke’s Law and Spring constants

Goals Analyze the relationship between how far a spring is stretched (Δx) and the force required to hold it at that distance. Develop a model for energy in a spring based on (ΣE) + W = (ΣE) If the spring has no initial energy, then the work done on the…Read More
