Exploring the Physics of Work and Power in Sports

What is the formula for power in physics?

• Power = Force / Distance

• Power = Work / Time

• Power = Distance / Time

• Power = Force x Velocity

In which unit is power measured?

• Joules

• Newtons

• Watts

• Meters

What happens to power if you increase the force or distance?

• Power decreases

• Power remains the same

• Power increases

• Power becomes zero

What is the effect of decreasing the time on power?

• Power decreases

• Power remains the same

• Power becomes zero

• Power increases

In the sled pull example, what force is being opposed?

• Electrostatic force

• Gravitational force

• Frictional force

• Magnetic force
