4. In the diagram below, two objects of the same size and mass are released from rest at the starting position. Object 1 was released before Object 2 was released. The diagram below shows the positions of Objects 1 and 2 a short time after both were released.

Both objects have the same amount of kinetic energy.
Both objects have the same amount of kinetic energy.
Neither object has any kinetic energy.
Object 2
In the given scenario, when the objects are released from rest, they start moving due to the force of gravity. Both objects have the same size and mass. As they move downwards, their gravitational potential energy gets converted into kinetic energy.
Since the objects are released at the same height and have the same mass, they both experience the same gravitational force and accelerate at the same rate. Therefore, they have the same amount of kinetic energy.
So, the correct response is: Both objects have the same amount of kinetic energy.
To determine which object in the figure has the least amount of kinetic energy, we need to understand what kinetic energy is and how it is calculated.
Kinetic energy is the energy of an object due to its motion. It is directly proportional to the mass of the object and the square of its velocity. The formula for kinetic energy is:
Kinetic Energy = (1/2) * mass * (velocity)^2
From the given information, both Object 1 and Object 2 have the same size and mass. However, the diagram does not provide any information about the velocities of the objects.
Since both objects were released from rest at the starting position, it can be implied that their velocities are equal. Therefore, since the masses and velocities are the same for both objects, they will have an equal amount of kinetic energy.
Hence, the correct response is: Both objects have the same amount of kinetic energy.
