HSC Physics Space 1. The Earth has a gravitational field that exerts a force on objects both on it and around it Define weight as the force on an object due to a gravitational field Mass is a measure of the amount of matter in an object‚ it is measured in kilograms (kg). The weight of an object is a measure of the force with which it is attracted by a gravitational force‚ it is measured in Newtons (N). It is directly related to the strength of the gravitational field at a point where the object

Experiment N | Kinetics of the Depolymerization of Diacetone Alcohol via Basic Catalysis | | Ingrid Tafur -5672578 | 2/11/2011 | CHM233O Partner: Laura Marrongelli Demonstrator: Cheryl McDowall Objective The rate constant of the depolymerization of diacetone alcohol via basic catalysis was determined by monitoring the change in volume as a function of time at constant temperature of a pseudo first order reaction where the species in excess was sodium hydroxide. This was accomplished

HSC Physics Notes - Space 9.2 - 1. The Earth has a gravitational field that exerts a force both on it and around it 1. define weight as the force on an object to a gravitational field Mass is the measure of how heavy an object it. Every object has a mass which is static and does not change with any force exerted on it or from it. However‚ weight is the force which is exerted upon an object when it comes into contact with or nearby a gravitational field of some strength. Weight is a force ஃ a vector

Figure 1.1 The Air Track A photogate is a u shape measuring device that is placed above the track. An infrared light emitting diode (source) and a photodiode (sensor) are placed on each side of the U-shaped frame. The photogate is considered unblocked as long as the sensor is picking up the

Why an ice cube at 0°C is more effective in cooling soft drink than the same mass of water at 0 °C? Enthalpy of fusion is the change in enthalpy resulting from heating a given quantity of a substance to change its state from a solid to a liquid. The temperature at which this occurs is the melting point would
