CP- Investigating Acceleration

Question 1

What is the method (trolley practical)?

Answer 1

1. Prop up one end of the ramp and place the trolley on it. Set up light gates and pulley.
2. Adjust it until the trolley moves on its own.
3. Stick a piece of card to the top of the trolley. Measure the length of the card and record.
4. Find the mass of the trolley and record.
5. Put mass on the end of the string.
6. Release the trolley and record the speed and time from one light gate to another.
7. Put mass on top of the trolley and repeat step 6.
8. Repeat this for the other masses, FOR HOW MASS AFFECTS ACCELERATION.

For force on acceleration, start the masses on top of the trolley and having one mass on the string. Carry on putting the masses in the string until there are none left.

Question 2

What can you conclude about the relationship between the mass and acceleration?

Answer 2

As the mass increases, the acceleration decrease.

Question 3

What happens to the force if the acceleration increases?

Answer 3

It also increases.
