What does the law of conservation of energy tell us?
Energy is created and destroyed all of the time.
Energy can not be created or destroyed.
Energy does not exist at all.
Energy can be created but not destroyed.
Which of the following statements about speed and velocity is correct?
Only velocity includes the direction an object is traveling.
Speed and velocity both describe how an object is speeding up.
Speed describes how an object is changing its direction.
when a train increases its velocity its momentum
decreases
remains unchanged
increases
is transfered to its surroundings
When a bowling ball hits a bowling pin
the momentum of both pin and ball increase
the momentum transfers from the pin to the ball
the momentum of both pin and ball decrease
the momentum transfers from the ball to the pin
the law of conservation of momentum states that when two objects collide their combined momentum
increases after the collision
remains the same after collision
decreases after the collision
cannot be determined after the collision
according to newton's third law, if an action force is a cue ball hitting a billiard ball, then the reaction force is
exerted on the table
exerted on the other billiard balls
no present
exerted by the billiard ball on the cue ball
While kicking a soccer ball outside, Cameron accidentally gets it stuck in a tree. So, she decides to climb the tree to get it down. As the ball falls to the ground, its ...
PE decreases; KE decreases
PE remains constant; KE increases
PE decreases; KE increases
PE increases; KE decreases
After safely climbing back down, she kicks the ball high into the air again — but away from the tree. As the ball sails upward, its ...
