Answer 3

[AI-generated answer — Explain Bot]

b. Some objects have energy due to their motion. This is called kinetic energy. When an object's speed gets faster, this kind of energy increases.

To understand why this happens, you need to consider the formula for kinetic energy:

Kinetic Energy (KE) = (1/2) * mass * velocity^2

From this formula, we can see that kinetic energy depends on two factors: the mass of the object and its velocity (or speed).

1. Mass: The mass of an object refers to the amount of matter it contains. It is a measure of the object's inertia or resistance to changes in motion. The greater the mass of an object, the more kinetic energy it has for any given velocity.

2. Velocity: Velocity refers to the speed of an object in a given direction. It is a measure of how fast the object is moving. When an object's speed increases, its velocity increases as well. Since kinetic energy depends on the square of velocity, a small increase in speed results in a much larger increase in kinetic energy. In other words, the kinetic energy of an object increases exponentially as its speed increases.

Therefore, when an object's speed gets faster, its kinetic energy increases. This is because the object's increased speed results in a higher velocity, which, in turn, leads to a greater amount of kinetic energy.
