Explain the concept of momentum in your own words.

• Momentum is the product of an object's mass and its velocity.

• Momentum is the energy stored in an object.

• Momentum is the resistance of an object to change its motion.

• Momentum is the force of gravity acting on an object.

What is an example of an inelastic collision?

• A ball hitting a wall and bouncing back with the same speed

• A person catching a ball and absorbing its momentum

• Two cars colliding and becoming tangled together

• Two cars colliding and bouncing off each other

Describe the difference between inelastic and elastic collisions.

• In both inelastic and elastic collisions, kinetic energy is not conserved and the objects stick together after the collision.

• In an inelastic collision, kinetic energy is conserved and the objects bounce off each other after the collision.

• In an inelastic collision, kinetic energy is not conserved and the objects stick together after the collision. In an elastic collision, kinetic energy is conserved and the objects bounce off each other after the collision.

• In an elastic collision, kinetic energy is not conserved and the objects stick together after the collision.

Explain the concept of conservation of momentum in your own words.

• Conservation of momentum only applies to objects at rest

• The momentum of a system decreases over time

• The total momentum of a closed system remains constant if no external forces act on it.

• Momentum is only conserved in open systems

What is an example of an elastic collision?

• Collision of planets

• Collision of cars

• Collision of billiard balls

• Collision of clouds

How does kinetic energy change in a collision?

• It always increases in a collision

• It always decreases in a collision

• It can increase or decrease depending on the type of collision.

• It remains constant in a collision

How is momentum conserved in a collision?

• Friction between the objects

• Conservation of momentum principle

• Conservation of energy principle

• Acceleration of the objects

What happens to the kinetic energy in an inelastic collision?

• It increases exponentially

• It is transformed into other forms of energy.

• It remains the same

• It disappears completely
