The total momentum of 2 marbles before a collision is 0.06 kg m/s. No outside forces act on the marbles. What is the total momentum of the marbles after the collision?
0.06 kg m/s remains the same
According to Newton's third law of motion how are action and reaction forces related?
Action and reaction work in pairs.
Why is it important for drivers to allow more distance between their cars when they travel at faster speeds?
Because the higher the velocity (speed) the longer it takes to decrease momentum and come to a stop.
What would happen if you tried to catch a ball when you were standing on roller skates?
The force of the ball would push you backwards.
What is momentum?
The product of an objects mass and velocity.
What is the momentum of a parked car.
Zero
State Newton's third law of motion
for every action there is an equal but opposite reaction
What is conservation of momentum?
in the absence of outside forces the total momentum of objects that interact does not change
