The scientist throws these two rocks with the same amount of force.
The larger rock moves slower. Why?
He decides to test 3 rocks of the same mass and graph the final speed of the rocks on different windy days.
What rock has the slowest final speed?
Rock A
Rock B
Rock C
He decides to test 3 rocks of the same mass and graph the final speed of the rocks on different windy days.
Why does rock C move the slowest?
The rock is heaviest
The rock wasn't thrown as fast
The rock had more air resistance
The rock had more friction
Our mad scientist has decided he will drop a rock at the top of a mountain where there are fewer air particles. How will this change the way the rock moves as it falls to the ground?
The rock will hit the boy.
The rock will move faster
The rock will move slower.
The rock will move the same.
The scientist wants the rock to have more kinetic energy when it hits its targets.
