Which characteristic will be affected by increasing the speed of an object from 30 meters per second ( ms
) to 40 meters per second( ms
)?(1 point)
A. weight
B. kinetic energy
C. mass
D. gravitational attraction
answer the question with the answers above
B. kinetic energy
The characteristic that will be affected by increasing the speed of an object from 30 meters per second (ms) to 40 meters per second (ms) is the kinetic energy (B).
To determine which characteristic will be affected by increasing the speed of an object from 30 meters per second (m/s) to 40 meters per second (m/s), you need to understand the relationship between speed and the various characteristics mentioned.
A. Weight: Weight is the force experienced by an object due to gravity. It is dependent on the mass of the object and the acceleration due to gravity. Changing the speed of an object does not directly affect its weight.
B. Kinetic Energy: Kinetic energy is the energy possessed by an object due to its motion. The kinetic energy of an object is directly proportional to its mass and the square of its velocity. Increasing the speed of an object from 30 m/s to 40 m/s will result in a greater kinetic energy, as the velocity is squared in the equation.
C. Mass: Mass is a measure of the amount of matter in an object and is independent of its speed. Increasing the speed of an object does not affect its mass.
D. Gravitational Attraction: Gravitational attraction is the force of attraction between two objects due to their masses. The speed of an object does not directly affect the gravitational attraction between objects.
Based on the explanations above, the characteristic that will be affected by increasing the speed from 30 m/s to 40 m/s is B. Kinetic Energy.
