Apparatus for the Study of the Dependence of the Acceleration of the Body on Force When the Mass Remains at C.
Product Code : SCL-PL-11811
Apparatus for the Study of the Dependence of the Acceleration of the Body on Force When the Mass Remains at C. (SKU SCL-PL-11811), where "C." stands for constant, is a cart-and-track set for investigating Newton's second law: with the mass held fixed, the acceleration of a cart increases in proportion to the applied force. It serves Class 9 and Class 11 physics and college mechanics labs. Science Lab Supplies manufactures the set in its Plot 448 factory, HSIIDC Industrial Area, Saha, Ambala, India, and quotes schools, colleges, tender contractors and distributors without agents.
Specifications
Carts, tracks, gates and masses of this second-law set are separated into single rows below.

Applications and Experiments for the Acceleration and Force Apparatus
The apparatus is used to show that, for a body of constant mass, acceleration is directly proportional to the net force, the core of Newton's second law F = ma. Students change the hanging load, measure the cart's motion along the track and plot acceleration against force.
- NCERT Class 9 science (Force and Laws of Motion): the second law of motion, timing runs with a 1/100 s Digital Stopwatch.
- NCERT Class 11 physics (Laws of Motion): F = ma and the effect of net force, with heavier hanging loads taken from the Mass Set with Hangers.
- Comparing motion on the straight track with motion on the curved track.
- College and polytechnic mechanics labs: graphing acceleration against applied force.
Standard Scope of Supply
The set is supplied with two carts (primary and secondary), two 1.5 x 0.3 m tracks for straight and curved motion, primary and secondary gates with mounting accessories, a box of hooked masses of 50–100 g, left and right plastic side clamps and a demonstration table for the experiment.
Packing, MOQ and Lead Time
Quotations cover a single set or a quantity for a full mechanics laboratory, each stating packing, delivery time and price for the number requested. You can include other mechanics lab equipment in India from the range on the same quotation.
Science Lab Supplies holds an Importer-Exporter Code, which means it can ship to buyers in Peru, Egypt, Iraq, Nigeria, Kenya and Ghana. For a second-law bench price, list the sets in the enquiry cart or describe your needs on the contact page; bid paperwork is covered on the lab tender page.
Frequently Asked Questions
What law does this apparatus investigate?
Newton's second law. Keeping the cart's mass constant while changing the applied force with hooked masses shows that the cart's acceleration rises in proportion to the force.
What size are the carts and tracks?
Each cart measures 290 x 140 x 90 mm and weighs 0.87 kg, and the two tracks are 1.5 x 0.3 m, one for straight-line movement and one for curved movement.
Is Science Lab Supplies the manufacturer or a trader?
Carts, tracks and fittings for this set are made at the Science Lab Supplies facility in Saha, Ambala, India; the company is the manufacturer, and the same facility prepares your quotation.
What does "at C." mean in the name?
It is short for "at constant", meaning the body's mass stays the same throughout the experiment while the applied force is varied from one run to the next.
