Factors that impact kinetic energy include mass and velocity. The kinetic energy of an object is calculated using the equation KE = 1/2 * m * v^2, where m is the mass of the object and v is its velocity.
In regards to the student's claim, it is not possible to determine if she is correct without knowing the mass or velocity of the ball. The height from which the ball is dropped does not directly impact its kinetic energy, as kinetic energy depends on mass and velocity.
On a roller coaster, the kinetic energy is highest at the bottom of a hill or at any point where the velocity is at its maximum. This is because kinetic energy is directly proportional to the square of the velocity.
For the diagram of the two objects released at different starting points, it is not possible to determine which object has more kinetic energy without knowing the mass and velocity of the objects. The position alone does not provide enough information to compare their kinetic energies.
If two cars have equal mass but different velocities, the car with the higher velocity will have more kinetic energy. Kinetic energy is directly proportional to the square of the velocity, so the car with the higher velocity will have a greater kinetic energy.
What factors impact the kinetic?
The student claims that a ball dropped 3.0 meters would have fewer than 96 joules of kinetic energy up hitting the ground. Is she correct? Why?
Where is the roller coaster's kinetic energy highest?
On the ramp shown below, a student releases two identical objects at different starting points. The student releases Object 1 first. The diagram below shows the positions of Objects 1 and 2 in motion.
