You can show Newton's second law, which is written as $F = ma$, with a fun experiment using a toy car, some weights, and a ramp. Here’s how you can do it:

What You Need:

• A toy car
• A ramp (you can make this from a piece of wood or cardboard)
• Weights (like small bags of rice or coins)
• A stopwatch
• A measuring tape

Steps to Follow:

1. First, set the ramp at an angle and measure how high it is.
2. Next, put the toy car at the top of the ramp. Let it roll down and use the stopwatch to time how long it takes to get to the bottom.
3. Now, add some weights to the car. Do the experiment again and time it once more.

What to Look For:

• As you add more weight to the car, pay attention to how it speeds up or slows down.
• You can even use the formula $F = ma$ to figure out the force and see how everything fits together.

This hands-on project helps you understand how force, mass, and acceleration work together!
