Total questions: 13
Worksheet time: 7mins
What is the SI unit for angular displacement?
newtons (N)
degrees (°)
radians (rad)
meters (m)
What is the formula for angular velocity?
ω = θ * t
ω = θ/t
ω = θ + t
ω = 2πf
If a cyclist has an angular displacement of 6.28 radians, how many complete revolutions have they made?
0.5 revolutions
2 revolutions
1 revolution
3 revolutions
What does centripetal acceleration depend on?
Mass and speed
Torque and force
Angular displacement and time
Linear velocity and radius
What is the formula for torque?
τ = F / r
τ = F - r
τ = F + r
τ = F * r
What is the angular acceleration if the final angular velocity is 20 rad/s and the initial angular velocity is 0 rad/s over 5 seconds?
2 rad/s²
3 rad/s²
4 rad/s²
5 rad/s²
Which of the following describes angular motion?
Movement with no acceleration
Movement in a straight line
Movement around a fixed point
Movement with constant speed
What is the relationship between linear velocity and angular velocity?
v = ω/r
v = rω
v = ω * r²
v = r/ω
What is the angular displacement for one complete rotation?
180°
2π rad
360°
π rad
If a wheel has a radius of 0.5 meters and is rotated by an angle of θ = 4π radians, what is the linear displacement?
2π meters
4π meters
8π meters
π meters
What is the centripetal acceleration of a car moving at 15 m/s around a circular track with a radius of 25 meters?
9 m/s²
15 m/s²
12 m/s²
6 m/s²
What is the angular velocity of a ceiling fan rotating at 50 revolutions per second?
100π rad/s
25π rad/s
10 rad/s
50 rad/s
What is the formula for angular acceleration?
α = ωf - ωo * t
α = ωo / ωf
α = ωf + ωo * t
α = (ωf - ωo) / t
