Total questions: 18
Worksheet time: 11mins
Uniform circular motion is the motion of an object in a circle with a ________________ but the direction of the velocity is continually changing with time.
uniform acceleration
constant velocity
constant speed
What is the relation between r, s and θ?
θ = rs
r = sθ
s = r/θ
s=rθ
What is the relationship between period, T and frequency, f?
T = f
T is directly proportional to f
T = kf
T = 1/f
What is the unit for angular displacement?
θ
rad
radish
theta
What is the velocity formula for uniform circular motion?
Angular velocity, ω defined as the rate of change of _________________
angular distance
uniform speed
angular displacement
What is the symbol for angular velocity?
θ
ψ
ω
Ω
What is the relation between v, r and ω?
v = rω
v = r/ω
ω = vr
ω = r/v
Which of the following depict the velocity of the ball?
A
B
C
D
what is the centripetal acceleration formula?
Which of the following statements is not true for a stone attached to a string and swung in a uniform vertical circular motion?
The magnitude of resultant force acting on the stone changes depending on the position of the stone in the circle.
The tension in the string is lowest when the stone is at the highest point of the circular motion.
The kinetic energy of the stone is constant throughout the entire circular motion.
The resultant acceleration is always directed towards the centre of the circle.
At the instant shown in the diagram, the car's centripetal acceleration is directed-
toward E
toward N
toward W
clockwise
