Acar that experiences no frictional force is started and caused to move. for the car to continue in that motion, the gas pedal would have to be used: at all times infrequently intermittently not at all a spacecraft is traveling in space far from any planets or stars. how much force is required to maintain the spacecraft's speed? 1/2 the mass of the spacecraft 1/4 the mass of the spacecraft none twice the mass of the spacecraft

On which of the following planets or celestial bodies will the mass of the object be the greatest? the earth because it has the greatest mass and therefore the largest force of gravity. the moon because it has the lowest mass and the weakest force of gravity. its mass will be the same on all because mass is constant, no matter the gravity. jupiter because it has the greatest mass and therefore the greatest force of gravity.

Aperson who has a weight of 165 pound-force [lbf] on earth is travelling to mars in a spacecraft. as long as the engines on the spacecraft are not operating, the person is essentially weightless during the voyage. during a course correction, the spacecraft undergoes an acceleration of 0.72 "g". the term "g" is the earth-normal gravity, so 1 "g" is 9.8 meters per second squared [m/s2]. this acceleration makes it "feel" like there is gravity in the spacecraft, and the person will have a perceived weight during the acceleration period, rather than feeling weightless.once the person reaches mars, what is the mass, in units of kilograms [kg], and weight in units of pound-force [lbf], of the person on mars? the gravity of mars is 3.71 meters per second squared [m/s2].

Aconstant force is applied to an object, causing the object to accelerate at 8 m/s2. what would the acceleration be if each of the following things happened (from the initial state)? (a) the force is doubled (b) the object's mass is doubled (c) the force and the object's mass are both doubled (d) the force is doubled and the object's mass is halved
