Momentum

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the equation p = mv.

Front

How do you calculate momentum?

Back

Momentum (p) is calculated using the formula p = mv, where m is mass and v is velocity.

Front

Which has more momentum: a stationary object or a moving object?

Back

A moving object has more momentum than a stationary object, as momentum depends on velocity.

Front

What happens to momentum in a collision?

Back

In a collision, momentum is conserved; the total momentum before the collision equals the total momentum after the collision.

Front

Why does a heavier object have more momentum than a lighter object at the same speed?

Back

A heavier object has more momentum because momentum is directly proportional to mass.

Front

If two objects collide and one is stationary, how much momentum does the stationary object gain?

Back

The stationary object gains all the momentum of the moving object if the collision is perfectly elastic.

Front

What is the relationship between mass and velocity in determining momentum?

Back

Momentum is directly proportional to both mass and velocity; increasing either will increase momentum.

Front

Why do football players in tackle positions tend to be larger?

Back

Larger players have more mass, which gives them more momentum, allowing them to tackle more effectively.

Front

What is the unit of momentum?

Back

The unit of momentum is kilogram meter per second (kg m/s).

Front

How does speed affect momentum?

Back

As speed increases, momentum increases, assuming mass remains constant.
