SUMMARY

The discussion centers on calculating the force required to accelerate a cart in a pulley experiment. Participants confirm that the force can be calculated using Newton's second law, F = ma, where 'm' is the total mass of the system, including both the cart and any weights on it. The acceleration is determined from the time it takes for the cart to travel a specific distance. Therefore, the correct approach is to multiply the total mass of the system by the calculated acceleration to obtain the force.

PREREQUISITES
  • Understanding of Newton's second law (F = ma)
  • Basic knowledge of pulley systems
  • Ability to measure time and distance accurately
  • Familiarity with calculating acceleration
NEXT STEPS
  • Research how to set up and conduct pulley experiments effectively
  • Learn about the effects of friction in pulley systems
  • Explore advanced applications of Newton's laws in physics
  • Study methods for accurately measuring acceleration and force
USEFUL FOR

Students in physics, educators conducting experiments, and anyone interested in practical applications of Newton's laws in mechanics.

I am doing an experiment where a cart is connected to a hooked hanger via pulley. The weight of the system is constant throughout the experiment, but weights are taken from the cart and connected to the hanger. We then record the time it takes the cart to travel a certain distance of time. I am able to calculate the acceleration. However, I am required to also calculate the force needed to accelerate the cart. Do I multiply the mass of the cart (with the weights on top included) by the acceleration or do I multiply the mass on the hooked hanger by the acc.? thanks

F = ma

mult the mass of the system by the acceleration...then you'll get the force
