What is a force?
The force two objects exert on each other when they rub against each other
What is friction?
An object at rest will stay at rest and an object in motion will stay in motion until a force acts on it
What is Newton's first law?
Acceleration depends on the object's mass and the net force acting on an object
What is Newton's second law?
For every action, there is an equal and opposite reaction.
What is Newton's third law?
The upward force used to send a rocket into space.
What is thrust?
the combination of all forces on an object
What is the Net Force?
This is where gravity acts in the universe
what is everywhere?
Newton's first law is also known as this
What is the law of inertia?
Newton's law is also known as this
What is the law of acceleration?
Newton's third law is also known as this.
Law of action and reaction
Any object traveling around another object in space.
What is a satellite?
A measure of the amount of matter in an obejct
What is mass?
This type of friction has to do with a solid object moving through a fluid
What is fluid friction?
Resistance to the change in motion
What is inertia?
To increase acceleration when mass stays the same, you need to change what?
What is the force?
Quantity of motion
What is momentum?
Any force that causes an object to move in a circular path
What is Centripetal Force?
gravitational force exerted on a person or object
What is weight?
This force is the upward force exerted on an object
What is air resistance?
Interia is dependent on this
What is mass?
To decrease acceleration when force is constant, mass must be what?
What is increased?
The more momentum an object has the harder it is to what?
What is stop?
This force changes the direction of the satellite in orbit.
What is gravity?
When the force of gravity is the only force acting on an object
What is free fall?
This number stands for acceleration due to gravity.
9.8 m/s2
An object with greater mass mean greater what?
What is inertia?
If we increase mass with a constant force, what happens to the acceleration?
What is decreases?
Momentum must always be what?
What is conserved?
Net force must be greater than this force to accelerate the rocket into space.
