Terminal velocity

In this activity you will use a small ball bearing and a viscous fluid like dish washing liquid or oil in a measuring cylinder

You need to film the fall of the ball and use tracker to analysis the data.

Discussion

Does the ball reach terminal velocity. What indicates this?

Assuming the effect of the ball is uniform. Draw a diagram showing all the forces acting on the ball. Determine the value of all the forces involved.

Assuming the force of fluid resistance on the ball is uniform, calculate the velocity the ball hits the ground at.
