What happens to the work done if the angle between the force and the direction of motion is 90 degrees?

• Work done is maximum

• Work done is zero

• Work done is minimum

• Work done is doubled

• Cosine

• Tangent

• Cotangent

In a real-world scenario, why is it important to consider the angle at which force is applied?

• To increase the speed of the object

• To maximize the work done

• To minimize the energy used

• To change the direction of motion
