Physics for IGCSE & O level - Forces And Motion (Section 1 - No. 16)
Which of the following is true about a car moving at a constant speed?
Its acceleration is zero.
It travels equal distances in equal intervals of time.
Its velocity is constant.
The slope of its distance-time graph is constant.
Penjelasan
When moving at a constant speed, there's zero acceleration. It covers equal distance in equal intervals. The velocity remains constant, and the graph's slope is constant.
