Research Question: How do unbalanced forces affect motion?
Design of the Experiment
The Controlling variable:
Lab Materials:
Procedures
Lab Set-Up
- Independent Variable: Force
- Dependent Variable: Acceleration
- Control: Mass of the object
- Constant: Total mass
The Controlling variable:
Lab Materials:
- A cart
- Hanging mass
- A low-friction path
- A motion detector
- Masses
Procedures
- A cart will be placed on a low-friction path;
- The hanging mass will be connected to the cart;
- We will put 0.65kg mass on the cart for the first trail;
- The mass on the hanging mass will be 0.05 for the first trail;
- We will move the some mass from the cart to the hanging mass each trail;
- As more mass added to the hanging mass, the object will move quickly due to the gravity on the hanging mass;
- We will use the motion detector to collect the data as the object moves in order to find the acceleration;
- After we get acceleration for each trail, we will calculate the force by time it with 9.8 m/s/s.
