Which option lists the factors that make up max energy transfer for a strike?

• A. Mass, Velocity, Time on contact
• B. Mass; Velocity
• C. Velocity; Time on contact
• D. Mass; Time on contact

Answer: (A)

Max energy transfer in a strike comes from the energy the striker brings to the collision and how long that energy can act on the target. The energy available to transfer is the striker’s kinetic energy, which depends on mass and velocity (1/2 m v^2). The actual transfer also hinges on how long the contact lasts—longer contact gives the force more time to do work on the target, delivering more energy before the impact ends. So, you need all three factors working together: mass, velocity, and time on contact. If you only consider mass and velocity, you’re accounting for how much energy could be available, but a very brief contact could waste much of that energy. If you ignore mass, you underestimate the available energy; if you ignore time on contact, you miss how much energy can be transferred during the collision. Hence, including mass, velocity, and time on contact best explains max energy transfer.
