3rd law
What is inertia?
The force that keeps an object moving in a circle
The tendency of an object to resist changes in its velocity
The force that pulls objects toward the center of the Earth
The reaction force that occurs in response to an action force
What is the effect of mass on inertia?
More mass means less inertia.
Mass has no effect on inertia.
More mass means more inertia.
Only shape, not mass, affects inertia.
What does it mean when forces are balanced?
The object will start moving in the direction of the larger force.
The object will accelerate.
The object will not change its motion.
The object will move in a circular path.
What would happen to a ball thrown in space (assuming no other forces act on it)?
It would eventually stop.
It would slow down due to gravity.
It would keep moving in the same direction at the same speed.
It would start moving in a circular orbit.
