Momentum Flashcards
What is the formula for calculating momentum?
Momentum = mass x velocity
True or False: Momentum is a vector quantity.
True
What are the units of momentum?
Kilogram meters per second (kg m/s)
In a closed system, what is the principle of conservation of momentum?
The total momentum of the system remains constant before and after a collision
Q
Q
How does an object’s mass affect its momentum?
Greater mass leads to greater momentum at the same velocity
What is the momentum of a stationary object?
Zero
What is the direction of an object’s momentum?
The same as its velocity
If two objects have the same momentum, which one has more kinetic energy?
The object with higher velocity
🎀

How is momentum related to Newton’s second law of motion?
Momentum product object’s mass and acceleration
What is the momentum of an object in free fall?
The momentum increases as the object accelerates due to gravity
How does an external force affect the momentum of an object?
An external force can change the momentum of an object by applying an impulse
What is the difference between elastic and inelastic collisions in terms of momentum?
In elastic collisions, the total momentum is conserved, while in inelastic collisions, some kinetic energy is lost
How is momentum used in sports?
In sports, momentum is crucial for understanding the movement and impact of players and objects in motion
