Free Fall Apparatus

Free Fall Apparatus is designed for studying and measuring the acceleration of gravity.

Experiment procedure: A steel ball is suspended with an electromagnet. The ball is released by a switch on the digital timer (download)to allow the free fall motion. During its descent (or “free fall”), the only force acting on the ball is the force of gravity. The digital timer (download) displays the fall time to the first photogate and the time to pass through the gate after the experimental run. Acceleration of the free fall motion of the steel ball is captured by moveable photogates and recorded by the digital timer (download). The steel ball which is caught after the free fall in a catcher (pocket) at the bottom of the post.

Coin and Feather Apparatus,Free Fall Tube

Coin and Feather Apparatus Free Fall Tube is designed to demonstrate free fall in a vacuum. This experiment demonstrates the coin and the feather falling with the same acceleration and striking the tube’s bottom at the same time. It shows the fact that objects of different masses fall at the same rate in a vacuum.The Coin and Feather Apparatus Free Fall Tube consists of a 90cm long and 5.5 cm in diameter plastic tube that is capped on both ends with a rubber stopper, with one end having a 1/4 NPT ball valve(stopcock) fitting for air evacuation.

When the tube is inverted under normal atmospheric pressure, students will see that the coin falls at a faster rate than the feather because of air resistance. When air in the tube is pumped out via a vacuum pump to create a vacuum in the tube, and the tube is inverted, the coin and feather in the tube will fall at the same rate because there is nothing causing resistance anymore in the tube.

Very occasionally the feather sticks at one and and must be dislodged by shaking the apparatus. A small vacuum pump (0201020060) or Laboratory High Vacuum Pump (0201020590) is required.

Friction Apparatus investigating frictions quantitatively

Friction Apparatus is designed to investigate static friction, sliding friction and rolling friction.Students can investigate friction qualitatively and quantitatively with our Friction Apparatus.

Friction is defined as the force that resists relative motion between the surfaces in contact when they move past each other. Friction is caused due to irregularities on the two surfaces in contact. when one object moves over the other, these irregularities on the surface get entangled, giving rise to friction. The greater the roughness, the more irregularities and the more significant will be the friction.Friction is helpful in most cases. As a force, friction depends on two external factors. One, Friction is dependent on the smoothness or roughness of the two surfaces between in contact with each other. When the surface is smooth, the friction decreases. While the surface is rough, the friction increases.The other, friction depends on the force that is acting on these surfaces.Friction increases when the force is applied along with the irregularities.There are four types of friction: Static friction, Sliding friction, Rolling friction and Fluid friction. Static friction is the friction that acts between the surfaces when they are at rest with respect to each other.In contrast, sliding friction is the resistance created between any two objects when sliding against each other. Similarly, Rolling friction is the force which resists the motion of a ball or wheel. While, Fluid friction is the friction that exists between the layers of the fluid when they are moving relative to each other.
