Experiment 3 – Forces are Vectors - College of Arts and ...
The mass is measured in kilograms [kg] and the force is measured in newtons [N]. Note The metal hangers on which the weights are hung have a mass of 5 grams each. This mass should be included in the hanging masses in your calculations. Exercise 1 Do weight hangers of equal weight always balance each other out? 1.

1 12. Rolling, Torque, and Angular Momentum
www.asc.ohio-state.eduH The velocity and angular velocity at the bottom of the ramp can be calculated using energy conservation. The kinetic energy can be written as a sum of translational and rotational kinetic energy: K tot = K tran cm + K rot rel to cm = 1 2 mv cm 2 + 1 2 Icm w 2 where w is the angular speed of the rotation relative to the center of mass and Icm ...

www.asc.ohio-state.eduElasticity The price elasticity of demand measures the sensitivity of the quantity demanded to changes in the price. Demand is inelastic if it does not respond much to price changes, and elastic if demand changes a lot when the price changes. • Necessities tend to have inelastic demand.

Lecture 1: Stationary Time Series
www.asc.ohio-state.eduIt is clear that a white noise process is stationary. Note that white noise assumption is weaker than identically independent distributed assumption. To tell if a process is covariance stationary, we compute the unconditional first two moments, therefore, processes with conditional heteroskedasticity may still be stationary.
7. Kinetic Energy and Work Kinetic Energy

To determine the mass of a liquid, we use an indirect technique called weighing by difference (Figure 1). First, we weigh a flask empty. Second, we add a given volume of liquid into the flask and reweigh.
