That solution should work, alternatively you could find the change in the gravitational potential energy and equate that change to the kinetic energy.Smartgurl said:Homework Statement
A 250 g object is dropped from a height of 150 m. What is the kinetic energy after falling to 100m
Homework Equations
V2^2 = V1^2 +2ad
Ek = 1/2 mv^2
The Attempt at a Solution
I used the kinematics equation to find my v2 then I used this to find Ek. I got the answer 120J but I'm not sure if I'm doing this right
The formula for calculating kinetic energy is KE = (1/2)mv^2, where m represents the mass of the object and v represents the velocity.
The height of the fall does not directly affect the kinetic energy. However, it does affect the velocity of the falling object, which is a factor in the kinetic energy formula. The higher the fall, the greater the velocity and therefore the greater the kinetic energy.
The mass of the object directly affects the kinetic energy. The greater the mass, the greater the kinetic energy, as seen in the kinetic energy formula.
Yes, the kinetic energy will be different for different objects, as it is dependent on both the mass and velocity of the object. Two objects with the same mass but different velocities will have different kinetic energies.
Yes, kinetic energy can be converted into other forms of energy, such as potential energy or thermal energy, depending on the circumstances of the fall. For example, if the falling object collides with another object, some of the kinetic energy will be transferred and converted into potential energy upon impact.
