ROTATIONAL MOTION Quiz

• Its angular displacement is zero
• Its angular acceleration is zero
• Its linear velocity is zero
• It is not moving

• It increases linearly
• It remains constant
• It increases quadratically with time
• It decreases exponentially

• Initial angular velocity
• Final angular velocity
• Total angular displacement
• Change in angular velocity due to acceleration

• They have different units
• Speed is always positive, velocity is not
• Angular velocity includes direction, while speed does not
• Speed applies to linear motion

• Force equals mass times acceleration
• Every action has an equal reaction
• A rotating body continues in uniform rotational motion unless acted upon by a net torque
• Energy is conserved
