SEHS B.2.1 HL quiz

What is a collision?

• When an object is thrown

• When one object moves faster than another

• When two objects come into contact and exert force

• When two objects are stationary

What is conserved during a collision?

• Mass

• Linear momentum

• Energy

• Velocity

What does the coefficient of restitution measure?

• The mass of the objects involved

• The distance traveled after a collision

• The ratio of relative velocity of separation to approach

• The speed of an object

What type of friction acts on a stationary object?

• Kinetic friction

• Dynamic friction

• Static friction

• Fluid friction

Which of the following is an example of dynamic friction?

• Walking on grass

• Pushing a stationary block

• Sliding on ice

• Holding a weight still

What is the formula for work?

• Work = Force + Distance

• Work = Force x Distance

• Work = Energy x Time

• Work = Mass x Acceleration

How is power defined in physics?

• The total force applied

• The distance covered over time

• The rate at which work is done

• The amount of energy used

What is the relationship between power and velocity?

• Power is always constant

• Power decreases with increased velocity

• Power is the product of force and velocity

• Power is independent of velocity

What is the main focus of muscular power in sports?

• Endurance

• Strength and speed of movement

• Flexibility

• Coordination

What is the purpose of optimizing power output in sports?

• To increase the weight lifted

• To maximize performance potential

• To reduce training time

• To improve flexibility
