Momentum

Front

What is momentum?

Back

Momentum can be defined as 'mass in motion.'

Front

Which object has more momentum: a 1000 kg truck moving at 7 m/s or a 500 kg car moving at 10 m/s?

Back

The truck has more momentum.

Front

What does momentum depend on?

Back

Momentum depends on the object's mass and velocity.

Front

What is the principle of conservation of momentum?

Back

When two objects collide, the total momentum before the collision is equal to the total momentum after the collision.

Front

How do you calculate momentum?

Back

Momentum (p) is calculated using the formula: p = mass (m) × velocity (v).

Front

If an object has a mass of 2 kg and is moving at a speed of 3 m/s, what is its momentum?

Back

The momentum is 6 kg·m/s.

Front

What happens to momentum when two objects collide and stick together?

Back

The total momentum before the collision is equal to the total momentum after the collision.

Front

Is momentum a scalar or vector quantity?

Back

Momentum is a vector quantity, meaning it has both magnitude and direction.

Front

What is the unit of momentum?

Back

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

Front

If a car's mass doubles but its speed remains the same, what happens to its momentum?

Back

The momentum doubles.
