Principle
The pupils should develop the notion of linear uniform motion experimentally, by deriving the speed of the powered car from the measurement of the distance and time. The experiment should be carried out with different distances and car speeds. ...
In this experiment, the students should explore the concept of acceleration by using uniformly accelerated motion as an example, and recognize the laws of the motion with aid of diagrams. By comparing the slopes obtained from s
The students should investigate the free fall of an object in the gravitational field of the Earth and record the fall with a recording timer and recording tape. From the data obtained they should determine the acceleration of the falling body, which ...
Pupils should examine a body's free fall under the earth's gravitational pull with the timer, a starting apparatus and a photoelectric gate, and they should determine the earth's gravitational acceleration from the information obtained.
The students use two cars joined under spring pressure to investigate impulse. When the cars are released from each other, they should examine how the impulse is distributed onto each of them and whether the total impulse (zero) is conserved.
A glider is repeatedly accelerated to a constant velocity by the mechanical starter system. The average velocity and the instantaneous velocity are determined at different distances from the starter system.
For determining the gravitational acceleration of the Earth (g) using the familiar distance-time relationship for accelerated movement with a falling sphere apparatus. A steel sphere is held in the release mechanism between a pin and a plunger, thereby closing a ...
Two air-cushioned gliders move toward each other from each end of the air track. Before they collide with one other, each passes a light barrier. A 6-decade digital counter measures and stores the times of those two events. After impact, which occurs between the ...
Two spheres of different mass can move freely along a trough. How do they behave when they are set in rotation at a constant speed around a central axis outside of the spheres? Flexible, rotating bodies - and therefore the terrestrial globe as well - deform in a ...
Why does a car "fly" out of a curve when the vehicle is travelling too fast?This experiment answers that question.A measurement cart is mounted on a track, which a motor sets in rotation. A string securely connects the measurement cart to a d ...
Normally liquids form horizontal surfaces under the influence of gravity. This changes, however, when other forces take effect. Along with gravity, a rotating liquid is also subjected to centrifugal force, which results in parabolic surfaces.
What happens when:
- Sitting on a swivel stool and holding a weight (10 kg) in each hand, a person extends their arms and then retracts them again while the stool is rotating?
- The person sitting on the stationary swivel stool is given a rotating gyroscope, the axis of whic ...
The moment of inertia of a body relative to a rotational axis that does not intersect its centre of gravity can be expressed as the sum of two characteristic moments of inertia: the moment of inertia of the mass concentrated at the centre of gravity and the mome ...
