PLEASE HELP

question 1

Kinetic energy is described as
O elastic
O decreasing energy
O movement
O stored energy

question 2

Kinetic energy depends on
O density and volume
O position and height
O heat and pressure
O mass and speed

question 3

If two trucks are moving at the same speed but truck A has a mass of 3,000 kg,. And truck B has a mass of 4,500 kg which statement is true?

O truck B will have a greater stopping distance
O Truck A will have a greater stopping distance
O Truck B has less kinetic energy
O Truck A has a greater kinetic energy

Question 4

If you throw a ball straight up into the air when is the kinetic energy the greatest?

O half the distance on this path traveling up in the air
O half the distance on ten path is traveling back down
O right before you catch it after it falls back down
O when the ball reached the highest point and stops briefly

Question 5
When is the kinetic energy of a pendulum the least?

O half the distance on the path traveling back down
O at the bottom of the swing
O at the top of the swim bc where it briefly stops before changing directions
O on the path beginning the upward swing
