Warm-up 4A

Front

What are the units for momentum?

Back

kgm/s

Front

What is the formula for calculating impulse?

Back

Impulse = Force × Time

Front

How do you calculate momentum?

Back

Momentum = Mass × Velocity

Front

What is the relationship between impulse and momentum?

Back

Impulse is equal to the change in momentum.

Front

If a 20 N force is applied for 2 seconds, what is the impulse delivered?

Back

40 Ns

Front

Which object has the greatest momentum: 5 kg, 8 kg, 2 kg, or 3 kg object moving at the same speed?

Back

The 8 kg object has the greatest momentum.

Front

What is the total momentum of a system?

Back

Total momentum is the vector sum of the momenta of all objects in the system.

Front

If an object has a mass of 4 kg and is moving at 3 m/s, what is its momentum?

Back

12 kgm/s

Front

What does a negative momentum value indicate?

Back

It indicates the direction of the momentum is opposite to the defined positive direction.

Front

How do you calculate the total momentum of a system with multiple objects?

Back

Add the momentum of each object: p_total = p1 + p2 + ... + pn.
