which of collowing situations describe a particle that might have a non-zero velocity? canbe more than one
A) a particle that has a constant position as a function of time
B) a particle that has its position changing as a fnction of time
c)when you graph the particle's accerleration, the slope of the ine is zero
d)a particle that is falling near the surface of the earth
B, C, D
In order to determine which situations describe a particle that might have a non-zero velocity, let's analyze each option:
A) A particle that has a constant position as a function of time: In this situation, the particle does not change its position, meaning it has zero velocity. Therefore, this situation does not describe a particle with a non-zero velocity.
B) A particle that has its position changing as a function of time: In this case, the particle is undergoing motion, as its position is changing over time. This implies that the particle has a velocity, which means it is moving. Hence, this situation describes a particle with a non-zero velocity.
C) When you graph the particle's acceleration, the slope of the line is zero: The slope of the acceleration-time graph represents the rate at which the acceleration changes. If the slope is zero, it implies that the acceleration remains constant over time. However, the velocity of the particle can still be non-zero, as long as it remains constant. Therefore, this situation can describe a particle with a non-zero velocity.
D) A particle that is falling near the surface of the Earth: If a particle is falling near the surface of the Earth, it is subjected to the force of gravity. As a result, the particle's velocity increases with time, and hence it has a non-zero velocity.
To summarize, situations B, C, and D describe particles that might have a non-zero velocity.
