1.1 GRAVITY AND GRAVITATIONAL FIELDS 1.1.1 Define weight as the force on an object due to a gravitational field. Weight is the force experienced by an object due to the presence of a gravitational field. This force is directly related to the strength of the gravitational field acting on an object and the mass of that object. m = mass‚ g = acceleration due to gravity m = mass‚ g = acceleration due to gravity Fg = mg Fg = mg 1.1.2 Explain that a change in gravitational

overall analysis. From the obtained aerodynamic measurements using a pitot-static tube mounted ahead of the airfoil at the test section‚ the actual velocity was determined and by relating it to the theoretical velocity‚ the velocity coefficient was calculated. The velocity coefficient varies for each baffle setting by a factor of decimals‚ thus the velocity coefficient can be used as a correction factor. Further‚ the coefficients of drag were calculated for the following angles of attack‚ 10o‚ 15o‚ and

PHYS111 Formal Report 2 University of Canterbury Campbell Moulder Abstract The force of gravity is said to be a constant of 9.81 ms-2 (3). This can be proved by measuring the projectile motion of a bouncy ball and plotting a ∆Vertical Velocity vs. Time graph‚ the gradient of which should equal the constant force (acceleration due to) of gravity. Our gradient value of 10.26±0.49 ms-2 is consistent with the actual value of 9.81 ms-2. Introduction A projectile is an object that has been

In this experiment‚ you will see how the range is related to the launch angle and initial velocity of launch. PURPOSE: Which launch angle will produce the greatest range? Which initial velocity of launch will produce the greatest range? HYPOTHESIS: VARIABLES: Independent:______________________________________________ How do you know this?

INTERMEDIATE MACRO-ECONOMICS CHAPTER 4 (MANKIW) THE QUANTITY EQUATION OF MONEY NOTES by: Chadia Mathurin THE QUANTITY EQUATION The Quantity Equation states that M xV = P x T where: M: is the money supply V: the velocity of money P: the prices of goods and services T: the number of transactions made in the economy. Making this equation applicable to the macroeconomy‚ T becomes Y where PY = nominal GDP. Rearranging the Quantity Equation with V as the subject‚ we get V= PY/M

3. Why don’t the terms depolarization and action potential mean the same thing? The terms depolarization and action potential differ because are excitable cells that communicate by transmitting electrical impulses that are capable of producing rapid electrical signals and depolarization in the interior surface of the membrane which becomes less negative and the exterior surface becomes less positive. Additionally‚ when depolarization reaches a certain threshold‚ an action potential is initiated

applied to a rigid body it changes the momentum of that body. If the momentum of an object changes‚ then either the mass or the velocity or both change. If the mass remains unchanged‚ as is most often the case‚ then the velocity changes and acceleration occurs. A force produces an acceleration‚ and the greater the force acting on an object‚ the greater its change in velocity and‚ hence‚ the greater its change in momentum. However‚ the change in momentum also depends on the duration of the force. The
