This law states that an object in motion remains in motion and an object at rest stays at lest unless an unbalanced force acts upon it.
What is Newton's First Law of Motion?
100
This law describes the relationship between force, mass, and acceleration.
What is Newton's Second Law of Motion?
100
I push on a table with a force of 500 N, how hard does the table push back?
500 N
100
This term describes force exerted on a mass as a result of gravity.
What is weight?
100
The effect of this type of force (balanced or unbalanced) is to stand still or move at constant velocity.
What is a balanced force?
200
A woman on a spaceship throws a ball into space, where no forces act on it. What will the ball do?
Continue moving at constant velocity/speed.
200
If the force on an object increases (without changing the object's mass), what will happen to the object's acceleration?
Increase.
200
Two people push against each other in outer space (no gravity) and they move away from each other at difference speeds. How can you tell which person has more mass?
The person with more mass will have a slower speed/less acceleration.
200
This terms describes the force of attraction that exists between two masses.
What is gravity?
200
This type of force results in acceleration (balanced or unbalanced).
What is an unbalanced force?
300
This term describes an object's resistance to change in motion.
What is inertia?
300
If mass is added to an accelerating object, the acceleration will __________________ .
Decrease.
300
Is it possible for two objects to be pushed with the same force but have different accelerations? Give an example.
Yes, because the objects have different mass/inertia. Give example.
300
This is the constant (number AND UNIT) we always use for acceleration when we are calculating our scientific weight on planet Earth.
What is 10 (m/s^2)?
300
What is the mass of a baseball that accelerates at 80 m/s^2 when hit with a force of 400 N?
What is 5 kg?
400
This term means a push or a pull.
What is force?
400
What are three changes you can make to a fan cart to decrease its acceleration?
Increase mass of fan cart
Decrease mass being pushed off fan cart
Use less rubber bands
Don't pull rubber bands back as far
400
A car and truck collide. Which object feels a greater force and which experiences a greater acceleration?
Same force. Car has greater acceleration.
400
This is the weight (NUMBER AND UNIT) of a person whose mass is 55 kg and is standing on the moon (where a = 1.6 m/s/s)
What is 88 N ?
400
Your weight will decrease when you go to this place.
What is the moon or outerspace?
500
What can you say about the forces acting on a car speeding up in a straight line?
They are unbalanced.
500
This is a 2 part question. An object has a mass of 56 kg.
a.) What is its weight on the earth?
b.) What is its mass on the earth?
a.) 560 N
b.) 56 kg
500
What is Newton's Third Law Pair to "Earth Pulls Ball"?
Ball pulls earth.
500
These are the standard units used for describing the values of Force, Mass, and Acceleration when using Newton's Second Law of Motion.
What are Newtons, Kg, and m/s^2?
500
State the action/reaction pair that causes a rocket to accelerate.
