PhyTorque equations and power developed by armature

What is the formula to calculate torque?

• Work x Energy

• Force x Distance

• Velocity x Time

• Mass x Acceleration

How do you calculate the torque of an object?

• Add the force applied to the object to the distance from the pivot point.

• Multiply the force applied to the object by the distance from the pivot point.

• Divide the force applied to the object by the distance from the pivot point.

• Subtract the force applied to the object from the distance from the pivot point.

What is the equation for armature power?

• P = V^2

• P = I^2

• P = V/I

• P = VI

How can armature power be calculated?

• By subtracting the current flowing through the armature from the voltage across the armature.

• By multiplying the current flowing through the armature with the voltage across the armature.

• By adding the current flowing through the armature to the voltage across the armature.

• By dividing the current flowing through the armature by the voltage across the armature.

What is the relationship between torque and speed?

How does torque affect rotational motion?

• It causes an object to move in a straight line

• It causes an object to rotate around an axis.

• It causes an object to shrink in size

• It has no effect on rotational motion

What is the impact of torque on rotational motion?

• It increases the speed of rotational motion

• It has no impact on rotational motion

• It affects the rate of change of angular momentum
