Unit 4 - Momentum Concepts/Vocab

Stand and Fighting as usual on a planet is traveling hundreds a miles every minute!

• WE SURE ARE

• NAH

• Earth is Flat

• Im Filler :(

• You sure are a buddy :)

Trains can't stop quickly or swerve

• Trains can stop quickly and swerve easily.
• Trains can stop quickly but can't swerve.
• Trains can swerve quickly but can't stop.
• Trains can't stop quickly or swerve because of their size and weight.

Why are trains so difficult to stop?

• Poor track conditions
• Large mass and velocity

• Inefficient engines
• Lack of brakes

What is Momentum?

What is Momentum?

• Momentum is the quantity of motion an object has.
• Momentum is the distance traveled by an object.
• Momentum is the force exerted by an object.
• Momentum is the speed of an object.

Momentum is how HARD it is to stop something that’s moving

• Momentum is a measure of how difficult it is to stop an object that is in motion.
• Momentum is the force that causes an object to move.
• Momentum is the speed at which an object is moving.
• Momentum is the distance an object travels in a given time period.

Momentum refers to the ------ that an object has.

• color of an object
• size of an object
• quantity of motion
• speed of an object

quantity of motion - what does it mean

• The speed of an object
• The weight of an object
• Measure of the amount of motion an object has
• The color of an object

Momentum is a VECTOR!

• False
• True
• Not sure
• Maybe

Vector vs Scale definition in physics

• A vector and a scalar have the same definition in physics.
• A vector and a scalar have no difference in physics.
• A vector has only magnitude, while a scalar has both magnitude and direction.
• Vector vs Scale definition in physics: A vector has both magnitude and direction, while a scalar has only magnitude.
