Which statement best describes how work and power are different?

Which statement best describes the differences between work and power?

To calculate work, we need to know both force and distance. In contrast, to calculate power, we need to understand force and velocity. Alternatively, to find work, we may consider energy and time, while power requires knowledge of energy and distance. Another approach is to link work with velocity and distance, whereas power can be determined using distance and time. Lastly, work relates to distance and force, while power relies on energy and velocity.

Question 2 (Multiple Choice Worth 2 points): A large box and a small box are placed on a table, and the same force is applied to both boxes. The large box moves two feet, while the small box moves one foot. Which movement demonstrates more work done? - The movement of the large box shows more work because it moved a greater distance. - The work done is equal since the same force was applied to both boxes. - The movement of the small box shows more work because it moved a shorter distance. - The work done is equal because both boxes moved in the same direction as the force.

Question 3 (Multiple Choice Worth 2 points): What is the correct description of work? - An action that causes no movement or reaction. - A force and motion in the opposite direction of the force. - A force and motion in the same direction as the force. - An action that causes movement and an opposite reaction.

Question 4 (Multiple Choice Worth 2 points): When discussing how power and work are similar, what would you emphasize? - That time is necessary to determine both work and power. - That knowledge of force is required to determine both work and power. - That energy is needed to calculate both work and power. - That velocity is essential to determine both work and power.

Question 5 (Multiple Choice Worth 2 points): In the scenario where a football player pushes against another player to block movement down the field, which term best describes this example? - Negative work - Positive work - Negative force - Positive force

Question 6 (Multiple Choice Worth 2 points): If less work is accomplished, which statement explains how this could happen? - There was less force applied, or there was less movement. - There was more force applied while movement remained unchanged. - More force was applied, and there was also more movement. - More force was applied, or there was more movement.

Question 7 (Multiple Choice Worth 2 points): If we reduce the force while keeping other factors constant, what impact will this have on the amount of work? - The amount of work will decrease because the distance will also decrease. - The amount of work will increase because the distance will decrease. - The amount of work will decrease as the distance increases. - The amount of work will increase because the distance increases.

Question 8 (Multiple Choice Worth 2 points): If you know the time and distance, how can you determine power if you also know force? - Watts - Energy - Joules

Question 9 (Multiple Choice Worth 2 points): What conditions must be met to consider something as work? - A force is applied to an object resulting in balanced forces. - The forces that caused the action were unbalanced, leading to movement in the opposite direction. - Action equals the reaction as a result of balanced forces. - Force applied causes movement of an object in the same direction as the applied force.

Question 10 (Multiple Choice Worth 2 points): If we know the force, distance, and time, what can we calculate? - Only power - Work and power - Only work - Neither work nor power.
