Rotational Motion Apparatus
Explore the relationship between linear (tangential) and angular velocity with this setup. A DC-driven motor produces various rotational velocity at various distances from the motor. Different radii are drawn on the disk and pegs can be positioned at specific radii. A photogate may be attached as well, so the time of one rotation is easily measured. Students will then make measurements to calculate the angular velocity, which will be constant for a given motor speed independent of position. However, the tangential velocity will vary based on the radius of the circular path. Kit includes a rotational table, ruler and calipers. Required but not included are a 6 V power supply and a photogate system.

Inertia Apparatus
Demonstrate the principle of inertia. Comprises an aluminum rod mounted on a plastic base. Rod has a recessed top to take the spherical ball. When striker is pulled back and released the card square is propelled, but the ball unaffected and falls into the recess. Supplied complete with spherical ball and card square.

Loop the Loop Triple Track
Understanding the principles of physics that occur on a roller coaster has become easier. This triple play apparatus consists of three tracks – one straight down, one with one loop, and the third with two loops. All three have different straight-up track lengths. At the end of each track is a catch sack to prevent losing the ball.
Straight track is 28 in. L, one loop track is 54 in. L with an 8 in. dia. loop, and two loop track is 70 in. L with a 3-1/2 in. dia. loop and 8 in. dia. loop, all on a 15-3/4 in. x 9-1/2 in. x 5/8 in. wooden base. Includes two steel balls (5/8 in. dia. and 3/4 in. dia.)

Balloon Puck Set
Apparatus may be used to explore the laws of motion without an air table and to study the inertia, constant velocity and acceleration and collisions in two dimensions. On flat smooth surface, the balloon puck can glide through without much resistance. Pucks ride on a film of air produced by air escaping from balloons, which are inflated and attached to the pucks. Kit includes two large pucks, two small pucks, four rubber stoppers, four tubes, four balloons and four rubber bands.

Trajectory Apparatus
This unique low-cost trajectory apparatus allows the students to study the trajectory of a projectile. A steel ball launches from a ramp and collides with the target plate that is equipped with marking paper to record the point of contact manually. Move the target plate to different positions and the exercise is to plot the full trajectory of the ball. The kit consists of a wooden plotting board, two wooden supports, one steel ball, one cello tape roll, four graph papers and four marking papers. The apparatus is provided with full instructions.

Collision in one Dimension
To demonstrate Newton’s third law of motion. Different number of balls is made to collide on a low-friction grooved track. Due to conservation of energy and momentum, we are able to predict a great deal about these collisions and to calculate relevant quantities after the collision occurs. With Five steel balls. 27″ track and instructions.

Mechanics
Dynamic Carts
Sturdy steel body to withstand rough handling, with three low friction balls bearing wheels and aligned axles to ensure their rolling along a true line without deviation to provide accurate data. Each cart weighs about 1.5 kg. The cart bed is covered with a rubber pad and the ends of the cart rise above the bed to carry a brick or any other mass. A clip is provided at one end of the cart to attach a tape. The pins of each cart fit with holes on the other so that they can be stacked to double the mass.
