Physics HSC Notes Space 1. Earth has a gravitational field that exerts a force on objects both on it and around it. K1 Define weight as the force on an object due to a gravitational field. Mass is the amount of matter within an object‚ measured in kg Weight is the force of gravity acting on an object’s mass measured in newtons (N). Weight is a force thus a vector quantity. K2 Explain that a change in gravitational potential

pulley system to lower the sling side of the beam and raise the heavy weight side. Then the rope holding down the sling side was loosed which‚ in turn‚ would drop the weight causing the sling attached to the arm to quickly raise up releasing the projectile. The trebuchet had a very versatile arsenal‚ it was capable of firing boulders‚ sharp wooden poles and darts‚ fire‚ burning tar‚ burning sand‚ dung‚ dead and sometimes mutilated bodies or even disease ridden bodies‚ body parts‚ and dead animals

on Application: Week Two Student’s Name MAT/205 Due Date Instructor’s Name For the example of a ball being thrown up into the sky and then landing on the ground‚ we can model a quadratic equation to show the path of the projectile at various points in time (projectile motion). That is to say‚ each point plotted on the graph (parabola) will be a measurement to this effect: Suppose a ball is thrown into the sky at a velocity of 64ft/sec from an initial height of 100ft. We would set the quadratic

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

listed below. Ideas are not limited to these‚ though. Remember also to have your instructor approve any ideas before proceding. Brainstorm some of your own ideas to improve the ballistic device as well. Make it more accurate/ consistent. Increase the range. Incorporate a fuel cell into the design. Create an automated loader. Incorporate a joystick. Have the arm go to specific angles automatically. Make the entire design mobile. Client Company: Hobby Spectacle‚ Inc. Target Consumer: Society

pistols; no long guns are available. The Firearms Training Unit has proposed that the department adopt the .223 caliber rifle for patrol officer use. The reasons for this proposal are: (1) pistols are inherently less accurate and have a shorter effective range than long guns such as rifles and shotguns‚ (2) pistol caliber bullets penetrate more heavily through interior walls than .223 rifle caliber bullets‚ which causes an increased risk of unintended persons being hit‚ and (3) pistol caliber bullets will

Functions of the skeleton: The skeleton provides the body’s bony framework. Its four key functions are: 1. To provide shape and structure 2. To protect the body’s organs 3 With muscle allows the body to move 4. To store calcium and produce blood cells JOINTS: A joint is where two bones meet. They are characterized by the amount of movement they allow. There are three main groups: 1. Immobile: Where the bones are jointed together and don’t move. eg: Bones of the skull 2. Cartilaginous:

The eye of a hurricane passes over New Orleans in a direction 60.0° north of west with a speed of 41.0 km/hr. Three hours later‚ the hurricane suddenly shifts due north‚ and its speed slows to 25.0 km/hr. How far from New Orleans is the hurricane 4.50 hours after it passes over the city? v1 = 41.0km/hr(cos30°‚ sin30°) = (35.5‚ 20.5) km/hr v2 = (0‚ 25.0)km/hr → D = v1×3hrs + v2 × 1.5hrs =Answer (105.9‚ 99) km A ship which can move at the velocity of v0 = (12‚ 6) m/s (x-axis: the West to the
