When using a reaction board technique to estimate center of mass, what should you tell your subject to do?

Use Newton’s third law (action-reaction) and Newton’s second law for rotation (α=τ/I) to complete the following statements by filling in the blanks. A tennis ball strikes a tennis racket off-center. The torque experienced by the ball is [1] the torque experienced by the racket. The resulting angular acceleration of the ball is [2] the resulting angular acceleration of the racket.

A force applied some distance from a fixed center of mass of an object will cause

You have two levers. For both levers, a force of 50 N is applied horizontally to the right and above the axis of rotation on both levers. Lever A: The force is applied close to the axis of rotation. Lever B: The same force is applied farther from the axis of rotation. Which of the following is true?

In which lever situation would the torque be the greatest if the force was the same for each lever?

You stand on a 5% incline and later on a 12% incline. In which situation is the limiting force of friction lower?

The resting membrane potential is established by cells having highly permeable membranes.

During walking, your lab group has set the braking peak to be negative and the propulsion peak to be positive.  Based on the anteroposterior force curve here, what is happening to the participant’s walking velocity?
