Newton's
How long will an object remain at rest according to Newton’s First Law of Motion?
It cannot rest.
Until noon.
Until an unbalanced force occurs.
As long as there are unbalanced forces acting on it.
What is inertia?
The tendency of an object to continue doing what it is currently doing and resist change.
The opposing force of gravity
Another name for unbalanced forces
The mass of an object.
Newton’s First Law of Motion states that an object in motion remains in motion and an object at rest will remain at rest until acted upon by an unbalanced force. This can also be called:
The law of action/reaction
The law of inertia
The law of force and acceleration
The law of universal gravitation

Newton's Second Law allows scientists to calculate _________________.
speed

Why do astronauts weigh less in space than they do on the Earth?
There is less air to cause resistance in space.
Their distance from Earth increases, so their mass decreases.
The gravity in space is lower than the gravitational pull on Earth.
The friction between astronauts and Earth is greater on Earth's surface.
