PHY 101 Kinematics in One Dimension Objective Question

Question

The equations of motion (e.g., v = v₀ + at, x = x₀ + v₀t + ½at²) are valid ONLY for motion that has
Options
A zero velocity.
B constant velocity.
C constant acceleration.
Correct Answer
D zero acceleration.
Correct Answer

Option C is the correct answer.

Detailed Explanation

These kinematic equations are derived from the definitions of velocity and acceleration under the specific assumption that the acceleration is constant (uniform). They are not generally valid for non-uniform acceleration.

Hint

These equations are often introduced together as a set. What is the key assumption that allows them to be derived in that simple form?
