Physics of Golf Putting

The video tutorial explores the physics behind putting in golf, focusing on energy, work, and power. It features professional golfer Suzann Pettersen and uses high-speed cameras to analyze the mechanics of putting. The tutorial explains how energy is transferred from the putter to the ball, the role of potential and kinetic energy, and how work and power are calculated during a putt. It emphasizes the importance of these physics concepts in understanding the dynamics of a successful putt.

What is the main focus of Suzann Pettersen when she is about to make a putt?

• Focusing on the crowd's reaction

• Calculating the exact force needed

• Visualizing the ball's trajectory

• Trusting her instincts and practice

Which of the following is NOT a physics concept demonstrated by putting?

• Energy

• Momentum

• Power

• Work

What type of energy is stored in a slightly compressed golf ball during a putt?

• Nuclear energy

• Thermal energy

• Elastic potential energy

• Chemical energy

According to the law of conservation of energy, energy can be:

• Created and destroyed

• Only destroyed

• Only created

• Neither created nor destroyed

How is work calculated in the context of putting?

• Distance divided by time

• Force divided by distance

• Force multiplied by distance

• Time multiplied by force

If a putter applies 105 Newtons of force over a distance of 1 millimeter, how much work is done?

• 105 millijoules

• 1 joule

• 10 joules

• 90 millijoules

What is the definition of power in the context of putting?

• The amount of force applied over time

• The amount of work completed over a period of time

• The speed of the putter head

• The distance the ball travels

How much power is used to accelerate a ball from zero to two meters per second if 90 millijoules of work is done in one millisecond?

• 50 watts

• 200 watts

• 103 watts

• 90 watts

If a golfer applies the same amount of work but at a slower rate, what happens to the power?

• It doubles

• It remains the same

• It decreases

• It increases

What happens to the control of the ball once it leaves the clubface?

• It is no longer under control

• It slows down

• It remains under the golfer's control

• It speeds up
