When a moving bumper car collides with a bumper car at rest, what will occur?

your bumper car will stop but you will continue to move forward until the force from your seat belt stops you

does a full shopping cart have more or less acceleration than and empty cart pushed with hard force?

less acceleration because it is heavier

they both hit the same time

why does a ball thrown horizontally follow a path that is curved downward? 

gravity

why do astronaunts orbiting space appear weightless 

because their body is in free fall

a cue ball rolls toward a billiard ball with a velocity of 1.0 m/s east. both have identical masses. what happens to the total momentum after the 2 balls collide? 

they would have equal momentum

according to Newton's first law of motion a moving object that is not acted on by an unbalanced for will....

stay in motion

300

terminal velocity

the constant velocity of a falling object when the force of air resistance is equal in magnitude and opposite is equal in magnitude and opposite in direction to the force of gravity

300

free fall

the motion of a body when only the force of gravity is acting on the body

300

projectile motion

the curved path that an object follows when thrown launched or otherwise projected near the surfaceof earth

400

inertia

the tendency of an object to resist being moved or if the object is moving to resist a change in speed or direction until an outside force acts on the object

400

momentum

a quantity defined as the product of the mass and velocity of an object
