Newton's 1st Law states...
An object at rest will remain at rest and an object in motion will remain in motion unless acted on by an outside force.
F = ma
For every action force, there is an equal and opposite reaction force.
Newton's 2nd Law states...
An object at rest will remain at rest and an object in motion will remain in motion unless acted on by an outside force.
F = ma
For every action force, there is an equal and opposite reaction force.
Newton's 3rd Law states...
An object at rest will remain at rest and an object in motion will remain in motion unless acted on by an outside force.
F = ma
For every action force, there is an equal and opposite reaction force.
According to the relationship (F = ma), what would be the acceleration of a 3 kg object being pushed by a 6 N Force?
18 m/s2
9 m/s2
3 m/s2
2 m/s2

A baseball is thrown by an astronaut in deep space. There are no other forces or air resistance. What happens to the ball after leaving the astronaut's hand?
It speeds up
It slows down
Its speed remains constant
The ball starts to curve downward
What pulls with more gravitational force?
The Earth pulling on you
You pulling on the Earth
Both forces are the same strength
