Law 1
What is speed?
Speed is how fast something is.
True or False
The greater the mass of an object being accelerated, the greater amount of the force need to make the object accelerate.
True.
For every action, there is __ _____ ___ ________ ________
an equal and opposite reaction.
What did Isaac Newton figure out?
He was the first scientist to precisely define gravitational force.
How many types of temperature are there?
3
What is the first law of motion?
An object at rest stays in rest.
What is the second law of motion?
"The acceleration of an object is equal to the net force acting on it divided by the object's mass."
What is the third law of motion?
For every action, there's is an equal and opposite reaction.
What is the law of universal gravitation?
What temperature is used for science and engineering?
Kelvin.
What is friction?
A force that opposes another force in contact.
How is acceleration produced?
When a force acts on a mass.
What happens when one object experts a force on a second object?
The second object exerts an equal and opposite force on the first object.
What is gravitational force?
The invisible force of an object that pulls things towards it.
How many (degrees) in the temperature of kelvin is the freezing point of water?
Trick! kelvin is not measured in degrees.
Give an example of the first law.
"A ball resting on the grass will remain resting on thee grass until a force is applied. such as a foot. After the kicked ball begins rolling, it will continue to roll until a force(friction) causes it to slow down."
Why does greater force need to be used when pushing a heavier/bigger object?
Since its heavier, it needs more force so that it can be pushed compared to a lighter object that doesn't need much force.
Explain the difference between action and reaction forces.
Action force is when the force of something collides with something else while reaction force is the reaction to the collision.
What has more gravitational force?
Tennis ball or Golf ball
Tennis ball
What is the lowest point of the temperature kelvin?(below zero and beyond) - (-100) - (0)
0
What is another name for the First law of motion?
The law of inertia.
What is the formula to calculate acceleration?
a=F/m F=ma
If a race car crashes into the side of a track, what force would that show an example of?
Action force.
Fill in the blank
All objects ------- each other through a --------- force of ------------- attraction.
attract - universal - gravitational
What temperature is it called when all thermal motion ceases in temperature of kelvin?
Absolute zero.
