Momentum
Gravity
Hodgepodge
100
The state in which one object’s distance from another is changing.
What is motion?
100
A push or a pull exerted on an object.
What is a force?
100
The two components used to determine momentum.
What are mass and velocity?
100
The force that pulls objects toward each other.
What is gravity?
100
The tendency of an object to resist its change in motion?
What is inertia?
200
Speed in a given direction.
What is velocity?
200
Balanced and unbalanced forces differ in this way.
What is unbalanced forces make objects move while balanced forces result in no movement.
200
The formula for calculating momentum.
What is mass x velocity?
200
Would it be easier to lift a recliner on the earth or on the moon? Explain your reasoning.
What is on the moon because gravity is weaker on the moon?
200
Mass is the amount of matter in an object while this is effect of gravity on an object.
What is weight?
300
The rate at which velocity changes.
What is acceleration?
300
3 things that force can do to an object.
What are stop (slow down), make it move (speed up), or change direction?
300
True or false: Momentum provides the ability for a moving object to stay in motion without an additional force.
What is true?
300
Do all objects in the universe weight the same? Why or why not?
What is no because the effects of gravity are different?
300
How are mass, acceleration, force related?
What is: the net force on an object depends on its mass and acceleration.
400
These are 3 examples of acceleration.
What are speed up, slow down, or change direction?
400
As mass increases, the force needed to move objects changes this way.
What is increases?
400
Which has more momentum: a 0.5kg baseball bat swung at 2.3m/s or a 1.2kg baseball bat swung at 0.8 m/s?
What is the 0.5kg baseball bat?
400
Which would hit the ground with more force: a penny or a feather? Why?
What is the penny because it has more mass?
400
These 2 words are used to describe action and reaction from Newton's 3rd law.
What equal and opposite?
500
What is the formula for calculating speed?
What is distance divided by time?
500
When the net force on an object increases, the object's acceleration changes this way.
What is increases (speeds up)
500
Two trucks of different mass roll down the same hill. Which will travel farther and why?
What is the heavier truck because it has more momentum due to its heavier mass?
500
Where is the acceleration of gravity faster - closer to the earth’s surface or further away? How do you know?
What is closer to the earth because attraction is stronger when 2 objects are closer together?
500
The of gravity does this as the mass of objects increases.
What is increases?
