### bppb6.iwp The animation shows a spherical object falling through a fluid with acceleration a = (k/m)v-g. The positive direction is up. The object has an intial position of 0 and is released from rest. The given ..

### fallcompare-simulation.iwp The green ball falls in a vacuum, while the red ball experiences a drag force from the fluid in which it falls. The acceleration of the red ball is a = -g + kv**2, where g = 9.8 N/..

### fallcompare-template.iwp Simulation of two objects falling from rest in a gravitational field. They experience air drag proportional to the square of the speed. The vertical acceleration is given by: a = -g+kv², where k is termed ..

### hookeslaw03.iwp A platform (black) is suspended from a fixed support by a rubber band. Weight can be added to the platform. When the red stick is pulled away, the platform with its weight will oscillate vertically ..

### incplane-template.iwp An object slides down an inclined plane. The angle of inclination of the plane and the coefficient of kinetic friction may be adjusted.

### incplane04.iwp An object slides down an inclined plane under the influence of gravity and kinetic friction. The plane makes an angle of 30 degrees with the horizontal.

### incplane05.iwp An object slides down an inclined plane. The coefficient of kinetic friction, which is initially 0, can be changed. The inclination of the plane, the initial x-coordinate of the block, and the initial velocity can also ..

### leaf.iwp The physical situation for this problem is like that of the falling leaf where the leaf experiences a lift force that is proportional to and perpendicular to its velocity. In this case, we treat the ..

### mass-bppb-3.iwp The animation allows you to check your calculated results against your measured results for a sphere falling through a fluid. Begin by entering your measurements in Input boxes. For the mass of the ball, enter ..

### projectile-drag-2.iwp The green projectile is subject to a v-squared drag force. The red projectile is subject to a v drag force.

### projectile-drag-lift-2.iwp The projectile is subject to a downward gravitational field, a drag force opposing the velocity and proportional to v-squared, and a lift force proportional to and perpendicular to the velocity.

### stopblock01.iwp An object moving horizontally is slowed by a force of kinetic friction. Adjust the initial velocity so that the right side of the block stops at the right-hand edge of the screen.

### turntable04.iwp A turntable accelerates uniformly. Three discs are held in place by static friction. In what order will the discs break free?

### turntable05.iwp A penny on a turntable slides off when the turntable reaches a certain frequency. What is the coefficient of static friction of the turntable? How does the result depend on the radius of the path?
