What is the evidence that supports the claim that, "The more mass an object has, the more kinetic energy it has."?
Which statement is the reasoning that connects the claim, "The more mass an object has, the more kinetic energy it has". and the evidence?
As the mass increases, the velocity stayed the same. All the balls traveled at the same speed.
As the mass increases, the kinetic energy decreases, thus if an object has more mass, there will be less kinetic energy and less power.
As the mass increases, the kinetic energy increases, thus if an object has more mass, like the bowling ball then it has the power to knock down more pins.
Thomas, Marcus, and Jesus are at a bowling alley, each choosing their favorite bowling ball. The balls come in different masses and are rolled at the same velocity. The table below shows the kinetic energy of different bowling balls rolled at the same speed. Use the information in the table to answer the question. Thomas used the plastic ball. Marcus used the resin ball the same size as Thomas's, but Jesus grabbed the heaviest ball he could carry. (Bowling Ball Mass, Velocity, and Kinetic Energy table). Take a closer look at these numbers: ✓ A 4 kg ball has exactly double the mass of a 2 kg ball. It also has exactly double the kinetic energy. ✓ A 6 kg ball has exactly double the mass of a 3 kg ball. It also has exactly double the kinetic energy. Who is most likely to knock down all the pins if they each roll the ball straight down the middle of the lane?
Thomas
Marcus
Jesus
Ms. Gutierrez
Richard is conducting a controlled experiment with toy cars of different masses speeding down a ramp. He makes sure to keep the speed the same. He observes how the kinetic energy changes as he increases the mass of the cars. Which statement is the reasoning that connects Richard's claim and the evidence?
There is no possible reasoning.
As the mass increases, the velocity stayed the same.
As the mass increases, the kinetic energy decreases, thus if an object has more mass, there will be less kinetic energy.
As the mass increases, the kinetic energy increases, thus if an object has more mass, there will be more kinetic energy.
Read the data table, then select the boxes to indicate what type of change, if any occurs. 1st column is the mass, 2nd is the height lifted, 3rd is the gravitational potential energy.
A round stone is replaced with a rectangular stone.
The potentional energy will increase.
The potentional energy will decrease.
The potentional energy will remain the same.
