If you are falling, which scenario will cause the greatest change in momentum when you land?Long time intervalShort time intervalMore information is needed Your change in momentum is the same no matter whatSmall force

If we eliminate the effects of air resistance, objects dropped from the same heightWill double their velocity every second, indefinitelyWill accelerate at the same rate but land at different times, depending on the shape of the objectWill accelerate at different rates, depending on mass Will land at different times, depending on surface areaWill accelerate at the same rate and land at the same time

Statement I: A body is thrown verticallyupwards. If air resistance is to be takeninto account, then the time duringwhich the body rises is greater than thetime of fall.Statement II: A body is thrown verticallyupwards and when it reaches half of itsmaximum height, its accelerationremains same

True or False: If you fall long enough and far enough gravity and air resistance will become equal

A freely falling body has a constant acceleration of 9.8 m/s2. This means that: Group of answer choicesthe acceleration of the body increases by 9.8 m/s2 during each secondthe speed of the body increases by 9.8 m/s during each secondthe body falls 9.8 m during each secondthe acceleration of the body decreases by 9.8 m/s2 during each secondthe body falls 9.8 m during the first second

When falling from a high building it is advisable to roll as you contact the ground.  Compared to contacting the ground and not rolling (assuming you fall from the same height), the purpose of this action is to:Question 22Select one:a.apply a smaller impulse to your body to change its momentum by decreasing the force appliedb.apply a larger impulse to your body to change its momentum by increasing the time over which the force is appliedc.apply the same impulse to your body to change its momentum by increasing the time over which the force is experienced and thereby decreasing the forced.apply a smaller impulse to your body to change its momentum by increasing the time over which the force is experiencede.apply the same impulse to your body to change its momentum by decreasing the time over which the force is experienced and thereby increasing the force
