100

The law stating that the total momentum of a system remains constant if no external forces act on it.

What is the Law of Conservation of Momentum

100

An elastic collision transfers this quantity and conserves this other quantity.

What is Kinetic Energy and Momentum in an elastic collision?

100

When two objects collide and merge together, this type of collision involves a loss of energy in the following forms.

What is heat, sound?

100

In this phenomenon, the total motion-related property of the system is maintained, but the objects move in opposite directions with equal and opposite values.

What is the conservation of momentum?

200

This equation describes the momentum of 2 objects in a system

What is
  vecP=m_a*vecv_a+m_b*vecv_b 
?

200

An elastic collision has this many objects before and after a collision.

What is the same amount?

200

After two objects collide inelastically, some of the system's energy is converted into heat, but this quantity remains the same before and after the collision.

What is momentum?

200

This property is increased in explosion even though momentum is conserved.

What is kinetic Energy?

300

The unit for momentum.

What is kg*m/s?

300
The velocity of object "b" after a collision with object "a".

What is the velocity of object "a" before the collision in an elastic collision before colliding with object "b"?

300

Two cars, one of mass 2000kg and the other with mass 1700kg. One car is initially at rest, and the other is traveling at +8 m/s. This value is the final velocity of both cars if they stick together after the collision.

What is +4.3m/s?

300

A 6 kg object at rest explodes into two pieces. One piece has a mass of 2 kg and moves at +4 m/s in the positive direction. The is the velocity of the other piece.

What is -2m/s?

400

The equation for for the final velocity of cart b after colliding and bouncing off of cart a.

What is 

vecv_(b_f)=(m_a*vecv_(a_i)+m_b*vecv_(b_i)-m_a*vecv_(a_f))/m_b

400

Object "a" mass of 2kg moving at +5m/s collides with object "b" mass of 3kg at rest. This is the final velocity of object "b" after the collision.

What is  vecv_(b_f)=+1.3m/s ?

400

A 10 kg cart moving at 5 m/s collides inelastically with a 15 kg cart at travelling at -4m/s. What is the final velocity of the combined mass after the collision?

What is -0.4m/s

400

A 500 kg rocket is at rest and explodes into two pieces. One piece has a mass of 300 kg and moves at +10 m/s. This is the velocity of the other object.

What is -6m/s?

500

A momentum of a system before the collision involving object "a" with mass 2kg and initial velocity +4m/s and object "b" with mass 3 kg and velocity -3m/s.

What is -1kg*m/s?

500

Two objects collide elastically. The first object has a mass of 4 kg and is moving at +5 m/s. The second object has a mass of 6 kg and is moving at +2 m/s. These are the final velocities of object "b" if object "a" has a final velocity of +1.4.

What is +4.4m/s?

500

A 3kg object and travelling at -6m/s collides with an object of unknown mass travelling at +3m/s. Their final velocity is -2.4m/s. The mass of the unknown object is____

What is 2kg?

500

An explosion is an inverse of this other phenomena.

What is an inelastic collision?
