Newton's first law is often called what other name?

When a cannon fires a cannonball, the cannon pushes the cannonball and the cannonball pushes the cannon with an ________ and _______ force
Equal/Opposite

If an object is at rest, what is the force that balances out gravity?
Normal Force

Define Newton's 1st Law
An object at rest (in motion) remains at rest (in motion) unless acted upon by an outside force
300
What unit measures acceleration?
(m/s2)
300
What does "conservation" mean?
To save something. Nothing is "lost". The principle by which the total value of a physical quantity or parameter remains constant in a system.

Inertia is directly related to an object's...
mass
400
An object accelerates 4 m/s2 when a force of 48 N applied to it. What is the mass of the object? Include units
12 kg

Explain why astronaut Mark accelerated at a different rate than the basketball if the force that Mark pushed on the basketball was also pushed from the basketball onto Mark.
Mark has a much larger mass, which means that since the forces were the equal (but opposite) his acceleration must be smaller, since F = m * a

Draw a free body diagram for the following situation: A skydiver jumps out a helicopter and experiences a downward acceleration. Consider air resistance.

Would it be easier to change the motion of a truck or a ping pong ball? WHY?
A ping pong ball because it has less inertia which means it has less resistance to change in motion
500
An object with a mass of 11 kg has a force of 33 N applied to it. What is the resulting acceleration of the object?
3 m/s2
500
If Newton's 3rd Law says that forces are equal but opposite, why do they not cancel out and we see movement of objects?
Because the forces are acting on DIFFERENT objects, not the same object
500
This object could be doing two different things. Describe those 2 types of motion.
1. At rest
2. Moving at a constant velocity (not accelerating)

As an ice skater pushes harder, they begin to move faster.
