Newtons laws
an object in motion will remain in motion unless acted upon by another force
Newtons first law of motion
Interia
The tendency of an object to resist a change in motion
any object that orbit around other objects in space.
What is a Satellite?
To increase acceleration of an object, you must reduce its mass or ______________ the applied force.
What is increase?
Newtons Second aw of motion
The acceleration of an object depends on the mass of the object and the amount of force applied.
is a characteristic of a moving object that is related to the mass and the velocity of the object. It is classified by strength and velocity.
What is Momentum?
Means Center seeking
What is Centripital
Action and reaction forces acting in opposite directions do not ________________ because they act on different objects
What is cancel out
For every action there is an equal and opposite reaction
Newtons third law of motion
the total momentum of any group of objects remains the same, or is conserved, unless
outside forces act on the objects
Satellites in orbit around Earth continuously fall toward Earth, but because Earth is curved they
travel around it.
If you lean against the wall the wall pushed back on you with an _____________ force
Equal
a statement of what will happen in any given set of circumstances.
What is a Scientific law?
is a force that causes an object to move in a circular path
What is Centripital force
When an object continues to fall at a constant speed but will no longer accelerate due to friction
Free Fall
An object traveling in a circle is constantly accelerating because it is constantly changing its ____________________
What is direction?
states that, in the absence outside forces like friction, the total momentum of objects that interact does not change.
What is conservation of momentum?
Formula for Momentum
mass x velocity
The SI unit for momentum
what is kg*m/s
The force that causes a satellite to move in a circle is ____________?
What is Gravity
