5
What does Newton's Third Law state?
Gravity is the strongest force in the universe
An object in motion will stay in motion, unless acted on by a force
For every action, there is an equal an opposite reaction
Forces equal mass times acceleration

The boat will stay still
The boat will sink
The boat will move forward
The boat will move back
11
How is acceleration defined by physics?
Acceleration is the same as force
Any change in speed
Acceleration is the same as speed
Any change in force
12
According to Newton's First Law, what will happen to an object at rest, unless acted on by an unbalanced force?
It will start moving
It will gain speed over time
It will change direction
It will remain at rest
13
What is the main factor that determines the force of gravity between two objects?
Their distance and mass
Their temperature and volume
