They should perform more trials
They should decrease the height of the drop
They should add a parachute (more surface area) to the egg pod
They should change materials to increase air resistance (friction) of the pod on its drop
Position A will result in the most PE because it has the most starting KE and starting force.
Position A will result in the most PE because it is at the highest starting position and moves against the force of gravity.
Position C has the most PE because it is already moving down the system with the force of gravity.
Position A moving to position B will result in the most KE because it had the most starting PE and energy is transferred allowing more KE to be present.
Position C to D will result in the most KE because it is at the lowest starting position, meaning it has the most assistance from gravity.
Position E has the most KE because the object has moved farther down the system meaning more energy has been transferred.
Diagram A adn B will move to the right
Diagram A and C will move to the right
Diagram A and B will remain motionless
Diagram B will remain motionless
Show your work here:
The first friend says that the force of one ball is only able to move one ball at a time, and after the collision it is impossible to have both balls move.
The second friend says that force exerted on each ball is equal causing both to move after they collide.
The third friend says that the force of one of the balls must be greater than the force of the other to cause both to move.
The fourth friend says that the force of the first ball increased before it collided with the second ball causing it to move
Design 1 is best because it gives off the least heat and reaches the greatest velocity
Design 2 is best because it gives off the most heat and reaches the highest velocity
Design 3 is best because it releases less heat and reaches lower velocities.
Design 4 is best because it travels at a high velocity without losing much heat in the process
