1.
The centripetal force on an object in uniform circular motion acts
along the velocity
towards the centre
away from the centre
at 45° to the velocity
2.
A ball on a string moves in a circle. The string breaks. The ball then
moves outward along a radius
stops
continues in the circle
moves along the tangent
3.
A car travels round a bend at constant speed. Its velocity
is constant
is zero
changes because the direction changes
equals its acceleration
4.
If the speed of an object in circular motion doubles at the same radius, the centripetal force needed
increases by 4 times
doubles
is halved
stays the same
5.
Which force provides the centripetal force on the Moon?
friction
magnetism
air resistance
gravity
6.
An object travels in a circle of radius 2.0 m with a period of 4.0 s. Its speed is about
0.50 m/s
3.1 m/s
1.6 m/s
12.6 m/s
