What is Newton's First Law of Motion?
An object will remain at rest or continue in uniform motion unless acted upon by an external force.
What is Newton's First Law of Motion?
An object will remain at rest or continue in uniform motion unless acted upon by an external force.
How does inertia affect athletes in sprinting?
Athletes must overcome inertia at the start of the race; they are at rest in the blocks and must exert force to start moving.
What is the formula for Newton's Second Law?
, where F is force, m is mass, and a is acceleration.
What does a larger mass require for the same acceleration?
A larger force is needed to achieve the same acceleration for a more massive object.
What is Newton's Third Law of Motion?
For every action, there is an equal and opposite reaction.
How does a swimmer demonstrate Newton's Third Law?
When a swimmer pushes water backward (action), the water pushes the swimmer forward (reaction).
What is the difference between scalar and vector quantities?
Scalar quantities have magnitude only, while vector quantities have both magnitude and direction.
What is the definition of force?
A push or pull that can change an object's motion.
How is speed defined?
Speed is the rate of change of distance, calculated as .
What is the formula for velocity?
Velocity is speed in a given direction, calculated as .
What does acceleration measure?
Acceleration measures the rate of change of velocity, calculated as .
What is momentum?
Momentum is defined as mass times velocity, .
What is impulse?
Impulse is defined as force times time, .
How is impulse related to momentum?
Impulse equals change in momentum: .
What factors affect projectile motion?
Speed of release, height of release, and angle of release.
How does the speed of release affect projectile motion?
Higher initial velocity results in a greater range.
What is the optimal angle for maximum range on level ground without air resistance?
The optimal angle is 45°.
Why might the optimal angle for projectile motion be lower in real sports situations?
Due to air resistance and other factors.
What is the effect of height of release on projectile motion?
A higher release point results in a longer time in the air, increasing potential range.
What is the relationship between angle of release and projectile motion?
The optimal angle depends on height difference, air resistance, and the purpose of the projectile.
