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
Which sport would benefit from minimizing friction?
Skiing
Basketball
Gymnastics
Football
What is the effect of static friction when pushing a stationary object?
It is less than the applied force
It is equal and opposite to the applied force
It has no effect
It is greater than the applied force
What is the main factor that affects the coefficient of restitution?
The angle of impact
The speed of the objects
The materials the objects are made of
The mass of the objects
In the context of sports, what does friction help with?
Increasing stability and control
Decreasing speed
Reducing energy expenditure
Eliminating resistance
