circle) were used to describe anomalies such as the retrograde motion of planets. Equants (a point which the centre of a planet’s epicycle moved at a uniform velocity) were used to approximate where planets would be at a certain time. Even though the Ptolemaic model had various defects‚ as astronomers assumed that all the planets revolved at a uniform rate‚ planets revolved in perfect circles‚ and didn’t explain the retrograde motion of planets that it was formulated to do; it was still widely accepted

Motion NCERT Chapter Questions and Answers and other Q & A Q1: An object has moved through a distance. Can it have zero displacement? If yes‚ support your answer with an example. Answer: Yes an object can have zero displacement even though it has moved through a distance. It happens when the object moves back to its original position i.e. final position coincides with the starting position. Example: Suppose an object travels from O to C and then comes back to original position O. Total

FORCE AND MOTION Scalars vs. Vectors Scalars | Vectors | A scalar quantity has only magnitude. | A vector quantity has both magnitude and direction. | Scalars can be added‚ subtracted‚ multiplied and divided just as ordinary numbers‚ i.e.‚ scalars are subjected to simple arithmetic operations. | Vectors cannot be added‚ subtracted and multiplied following simple arithmetic laws. Arithmetic division of vectors is not possible at all. | Example: mass‚ volume‚ time‚ distance‚ speed‚ work‚ temperature

Lebanese American University Classical Physics 3 . Projectile Motion Objectives: Students will measure the maximum height H and the range R of a projectile motion. They will study the effect of the shooting angle on H and R. Material used: 4 rulers‚ track‚ metallic ball‚ landing track‚ A4 white paper‚ red carbon paper‚ timer + supply‚ gun + protractor. Theory: A projectile is an object upon which the only force acting is gravity. There are a variety of examples of projectiles: an object

Experiment 4 Projectile Motion Introduction We examined projectile motion by observing a ball rolling down then leaving the ramp‚ thus becoming a projectile with a horizontal initial velocity. We measured the horizontal initial velocity using the photogate and computer. We measured the horizontal and vertical distances that the projectile traveled from the end of the ramp to when it hit the floor my using a meter stick to measure Experimental Set-Up In our experiment‚ we used the following:

hill. Determine the initial horizontal velocity of the soccer ball. Problem Type 2: A projectile is launched at an angle to the horizontal and rises upwards to a peak while moving horizontally. Upon reaching the peak‚ the projectile falls with a motion that is symmetrical to its path upwards to the peak. Predictable unknowns include the time of flight‚ the horizontal range‚ and the height of the projectile when it is at its peak. Examples of this type of problem are a. A football is kicked
