Distance, Velocity and Time: Equations and Relationship Do you remember the story of the tortoise and the hare? The tortoise and the hare decided to have a race. Everybody, most of all the hare, thought the hare would win the race because he hopped much faster than the tortoise plodded. We could say that the hare usually travelled at a much higher velocity than the tortoise. Velocity is the measure of the amount of distance an object covers in a given amount of time. Confident that his high typical velocity would allow him to cover the race distance in a short amount of time, the hare took a lot of breaks. Predict when a fast toy car can pass a slower toy car. A smooth, clear, level stretch of floor (two 2-meter stretches of flat Hot Wheels track is even better) Assistant 2 toy cars with adjustable speeds Tape measure Stopwatch or timer Graph paper Pencil Ruler Use your tape measure to mark off a distance of 1.5 meters from the starting line. Uniform velocity is a linear function, making them easy (and fun) to predict.

Practice Taking the HSA ~ HSA: High School Assessment Program ~ Practice Taking the HSA Teachers can use the mini-assessments on the public release forms to help diagnose student strengths and needs. The mini-assessments are organized by the content standards identified in the table below. Items on the mini-assessments were on previous forms of the actual assessment and have been released to the public to illustrate how content might be assessed. The mini-assessments include a combination of selected response, student produced-response and constructed response items. After students complete the online mini-assessments, they will receive the results of their performance online by standard, expectation, and indicator assessed. Assessment taking tools are also available through Pearson Educational Measurement Solutions.

How to Find Maximum Height of a Projectile Ever wanted to know how high and how fast you can kick a football? Turns out, it’s pretty easy to figure out. All you need to know is how far away from you the ball lands and how much time it spends in the air (the “hang time”). How can you find a projectile's maximum height? Given the hang time and distance traveled of a football, figure out how high it went, how fast you kicked it, and the angle at which it left the ground. Football Stopwatch Tape measure or a football field Calculator Pencil and paper Willing friend Kick the ball and, at the same time, start the stopwatch. You have calculated the speed at which you kicked the ball (in meters/second), the angle at which it launched, and how high you kicked it (in meters). The above may sound like a bunch of mathematical gobbledygook. The total time spent in the air combined with how far along the ground the ball went tells you everything you need to know about the ball’s horizontal velocity. Disclaimer and Safety Precautions

A Plasma Ball! What is it and How Does it Work? Grade Level: 6th - 9th; Type: Physics To determine what a plasma ball is and how it works. What is plasma? What are ions? What are inert gases? What is the Tesla coil and how is it used? The student will acquire basic information on the phenomenon called plasma and the applications of this unique coil. This science fair experiment also serves to acquaint students with the essential processes of sciencing such as the importance of the use of a control, of identifying dependent and independent variables, of data collection, of pictorial and or graphic presentation of data and of being able to make better judgments as to the validity and reliability of their findings. Plasma ball (available at toy stores) fluorescent light tube (available from local hardware store), a wooden stool or wooden chair (not metal) a few pennies and a multimeter (borrowed from the school`s physics lab).

Representation of Different Types of Motion by Simple Graphs In the previous experiment, we worked with constant velocity in one direction and found that the motion was represented by simple graphs whose slopes were straight lines. Here, you study the motion of a person going forward and back, fast and slow. You also measure the effect of speeding up and slowing down. motion sensor appropriate computer interface for the motion sensor (roughly) 8 inch by 10 inch piece of cardboard Attach a motion sensor to your computer. Figure 2-2 shows the result of someone moving backward and forward in such a way that they match the target motion pattern. Constant velocity in the positive direction (which in this case is defined as away from the motion sensor) is represented by a straight line on a distance versus time graph. Zero velocity means the distance stays the same over a given time interval. A curved line would be produced by accelerated motion (speeding up or slowing down). Each new phase of the motion contributes a separate segment to the graph.
Air Resistance > Experiment #13 from Physics with Vernier Recommended for High School. Loaded: 0% Progress: 0% Introduction When you solve physics problems involving free fall, often you are told to ignore air resistance and to assume the acceleration is constant. Air resistance is sometimes referred to as a drag force. When falling, there are two forces acting on an object: the weight, mg, and air resistance, –bv or –cv2. vT ∝ m or vT2 ∝ m If we plot mass versus vT or vT2, we can determine which relationship is more appropriate. In this experiment, you will measure terminal velocity as a function of mass for falling coffee filters and use the data to choose between the two models for the drag force. Objectives Observe the effect of air resistance on falling coffee filters.Determine how air resistance and mass affect the terminal velocity of a falling object.Choose between two competing force models for the air resistance on falling coffee filters.

ELATE This activity is about velocity, acceleration, and deceleration,as influenced by forces of friction and gravitation. And you will be introduced to a device called a ticker-timer. At the end of the activity, the learner should be able to: Describe how friction compensation happens on a runway. To set up this activity, the following equipment is needed: Trolleys, runways, ticker-timers, ticker tapes, and rulers. Set up the trolley to move on a horizontal runaway as shown in figure below (under the guidance of your teacher). Describe the various tapes that show uniform velocity and those showing accelerated motion. DETERMINING VELOCITY FROM THE TICKER TAPE Answer the following questions: If the frequency of the ticker timer is f, what is the time interval between two successive dots?. The following examples show various tapes each of length 8cm obtained using a ticker timer of frequency 50Hz. Discuss how to choose the interval for the initial and final velocities on the accelerated tape.
