Why is the gravitational potential energy of an object 1 meter above the moons surface less than its potential energy 1meter above earths surface?
a. the objects mass is less on the moon
b. the objects weight is more on the moon
c. the objects acceleration due to gravity is less on the moon
d. both a and c

The velocity of a curling stone is due east. what will be the direction of the momentum of the curling stone as it moves?

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to. in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?
