For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account. 2. Inertia - A property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force. 3. Potential Energy - Is the energy stored in an object due to its position in a force field or in a system due to its configuration.
must have constant velocity. must have zero momentum. 10. The inertial mass of a body may be defined as A. B. C. D. the ratio of the resultant force acting on the body to its acceleration.

Paulina Crisostomo Period 3 11/3/08 Motion Graphing Labs Lab 1: straight line motion- Aim- to measure and calculate the speed of an object Key Question- Will the objects go at a constant speed, increase, or decrease in speed? Hypothesis- I think the cars will have a constant speed at each of the distances they travel Materials- electric car, timer and meter stick Procedure- 1. Time the electric car going at a distance of 1 meter twice 2. Time the electric car going at a distance of 2 meters twice 3. time the electric car going at a distance of 3 meters twice 4. calculate the speed of each time you took Inferences- • I think the car will travel at a constant speed for all the distances • I think the car will travel at an angle instead of a straight line • I think that the car will have the same speed for all three distances Observations- • The car seemed to be going at a constant distance for the first meter • the car did not go in a straight line, it curved just like I predicted it would • the car had the same time for distances 2 and 3 • the car had about the same speed for the first meter compared to 2 and 3 • some other cars I watched did not go at a constant speed, but ours did analysis- 1. How does average speed relate to the distance covered and the time taken for travel?
G. TRUE or FALSE: The acceleration of a particle following a space curve lies in the normal plane. 2) Sketch the curve with the given vector equation, starting at t=0 . Indicate with an arrow the direction in which t increases. Be sure to include a few points to justify your graph. 8pts r(t) = cos t, sin t, sin
* Explain what a radian measure represents using the unit circle as a reference. Pie is represented by a real number constant and is the ratio of the circumference of a circle to its diameter. Its value is approximately 3.14159. Since the circumference of the unit circle is 2 Pie, it is implied that the radian measure of an angle of one revolution is also 2 Pie. So the radian is the measure of how close a degree is to a complete circle.
The distance between the forces is given by the Coulombs law through the use of the formula F=kq1q2/r2.0.1newtons = 8.99*109*3.2*10-6*7.7*10-7/r2 R= 555.78 Answer to question 3 • Potential difference between the two plates is equal to velocity which is equal to 6.0*106m/s • Force = mass *acceleration = 1.4*10-13*6.0*106 = -8254 nektons The speed of the particles are computed by the formula V=ED. This is equal to 8.5*10-6*0.15. This is equal to 84.1 Answer to question 4 Voltage = current *resistance. This implies that in this case while V is 5.0 and resistance is 1.0*103, current will be equal to 5/1.0*103, = 500 amps B the direction of the conventional current provides the electric charge movement from the positive side of the battery to its negative side as in indicated in the diagram below Answer to question 5 • This section focuses on the equivalent resistance of a circuit. The equivalent resistance will be equal to (5.0*102+1.00*103)2.
Apply this bias to all micromanometer measurements. 2. Connect the micromanometer, pressure transducer (voltmeter), and scannivalve to the Pitot tube in the subsonic tunnel. 3. Record the readings of the three instruments at eight different speed settings of the tunnel: 15, 20, 25, 30, 35, 40, 45, & 50.
Use algebra to find the time measured by Person A with respect to how he or she perceives the time measured by person B. 4.Person A is flying through space with Person B exactly 186,000 miles behind. When Person A wants to accelerate, he or she uses a flashlight to signal person B. This means they accelerate together and remain exactly 186,000 miles apart. Person A waits exactly 1 second to allow the light to reach Person B before he or she accelerates, so they remain 186,000 miles apart from their perspective.
