Here is a suggested experiment to investigate Newton's second law:
Materials:
- Cart
- Force meter or spring scale
- Timer
- Tape measure
Procedure:
1. Use the tape measure to mark a start and finish line on the floor, about 2-3 meters apart.
2. Place the cart at the start line and measure its initial mass.
3. Apply a force to the cart using the force meter/spring scale and record the applied force.
4. Time how long it takes the cart to travel between the lines. Use a stopwatch or timer on a phone.
5. Repeat the trial, gradually increasing the applied force and recording the new time.
