Card 1 of 24
How can an object moving in a circle have constant speed but changing velocity?
A
Momentum is calculated using p=mv\boxed{p=mv}p=mv.
B
The centripetal resultant force always acts towards the centre of the circle.
C
A straight line tangent to the circle at that point.
D
Its direction changes, so its velocity changes.
