In the February issue we looked at teaching speed and velocity. This is the biggie—perhaps one of the most difficult concepts in your course. You may find it okay to hurry through the concepts of speed and velocity because they are intuitive. But you cannot hurry through acceleration quite so quickly because it is not intuitive.
Students will investigate the motion of toy cars and collect data to analyze the speed of the vehicle between various points positions and overall speed. Students will then use the data to create graphs and analyze experiment reliability. Your Account. Summary Students will investigate the motion of toy cars and collect data to analyze the speed of the vehicle between various points positions and overall speed. Students will investigate motion and speed of toy cars.
Observations and predictions of various varioables type, size of toy will be made with other student groups. Critical thinking will be applied while discussing the reliablity of the investigation. Speed, constant speed, average speed, and acceleration will be investigated and recorded using data graphs.
This activity can be easily adapted for use in other settings, including the "vehicles" used. Equipment needed for each group of 6 students: Meter stick masking tape toy car worksheets found in the activity description. Any type of toy car may be used including , Matchbox Hot Wheels, wind-up, or remote control vehicles. To perform the tests, create a "race track" and position five students armed with stop watches at various points along the track.
Using a 5 meter "race track," mark off 1, 2, 3, 4, and 5 meter positions. As the car passes each point, the students should record the time in their data charts. Once the three trials are complete, head back to the classroom and use the data collected to analyze the speed of the vehicle between various points and overall speed. Students use the data to create graphs and analyze the reliability of their experiment. Challenges during this lab include keeping the car on the track, making sure it travels the complete distance, and making accurate time readings.
These are points for discussion as we determine if our tests are reliable. Worksheets lab sheets will determine whether or not students are achieving the learning goals. Observation of students inquiry during the investigation will be key to achievement of learning goals.
Physical Science -- Motion 1. The motion of an object can be described in terms of speed, direction and change of position. Explain how these graphs describe the object's motion.
Foundation Science for Engineers pp Cite as. So far our discussion has been about systems that are either at rest or in a state of uniform motion. This topic introduces the idea of accelerated motion but, for the moment, without any reference to the forces that cause it. Unable to display preview. Download preview PDF.
We head to the Porsche Experience Center Atlanta track to learn about the difference between speed and velocity. Different types of velocity are explored and we investigate how to find information from a position versus time graph. Obtain, evaluate, and communicate information about the relationship between distance, displacement, speed, velocity, and acceleration as functions of time. Plan and carry out an investigation of one-dimensional motion to calculate average and instantaneous speed and velocity. Analyze and interpret data using created or obtained motion graphs to illustrate the relationships among position, velocity, and acceleration, as functions of time. Obtain, evaluate, and communicate information to explain the relationships among force, mass, and motion. Plan and carry out an investigation to analyze the motion of an object using mathematical and graphical models.
How do you know if an object is in motion? Page 2. Speed, Velocity, and Acceleration. Page 3.
Barger, Vernon D. Last reviewed: April The time rate of change of velocity. Acceleration is a physics term that measures the rate of change of velocity per unit of time. Because velocity is a directed or vector quantity involving both magnitude and direction, a velocity may change by a change of magnitude speed or by a change of direction, or both.

The situation is analogous to throttling the speed of an automobile by rapidly "pumping" the accelerator. Review modal verbs of ability here Download this quiz in PDF here.

The velocity of an object is the rate of change of its position with respect to a frame of reference , and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion e. Velocity is a fundamental concept in kinematics , the branch of classical mechanics that describes the motion of bodies. Velocity is a physical vector quantity ; both magnitude and direction are needed to define it. For example, "5 metres per second" is a scalar, whereas "5 metres per second east" is a vector. If there is a change in speed, direction or both, then the object has a changing velocity and is said to be undergoing an acceleration. To have a constant velocity , an object must have a constant speed in a constant direction.
But, we have not developed a specific equation that relates acceleration and displacement. In this section, we look at some convenient equations for kinematic relationships, starting from the definitions of displacement, velocity, and acceleration. We first investigate a single object in motion, called single-body motion. Then we investigate the motion of two objects, called two-body pursuit problems. First, let us make some simplifications in notation.
In mechanics , acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities in that they have magnitude and direction. The magnitude of an object's acceleration, as described by Newton's Second Law ,  is the combined effect of two causes:. For example, when a vehicle starts from a standstill zero velocity, in an inertial frame of reference and travels in a straight line at increasing speeds, it is accelerating in the direction of travel. If the vehicle turns, an acceleration occurs toward the new direction and changes its motion vector. The acceleration of the vehicle in its current direction of motion is called a linear or tangential during circular motions acceleration, the reaction to which the passengers on board experience as a force pushing them back into their seats. When changing direction, the effecting acceleration is called radial or orthogonal during circular motions acceleration, the reaction to which the passengers experience as a centrifugal force.
