Physics SP015: Motion at Constant Velocity

Vocabulary flashcards covering kinematics concepts including constant velocity, zero acceleration, and displacement behaviors in various situations from the Physics SP015 lecture notes.

Zero acceleration

The state of an object that is moving at constant velocity.

Velocity at Point A ($0\,m$)

$$10.00\,m\,s^{-1}$$

Velocity at Point B ($10\,m$ from A)

$$10.00\,m\,s^{-1}$$

Velocity at Point C ($10\,m$ from A)

$$10.00\,m\,s^{-1}$$

Situation (i)

An object moves to the right, displacement increases, and velocity remains constant ($+$, right).

Situation (ii)

An object moves to the left, displacement decreases, and velocity remains constant ($a=0$, $v$ constant).

Situation (iii)

An object moves to the left, displacement increases, and velocity remains constant.

Situation (iv)

An object moves to the right, displacement decreases, and velocity remains constant.

Acceleration ($a$)

For an object moving at constant velocity, $a = 0$.
