What is Newton's First Law?
An object at rest stays at rest, and an object in motion stays in motion with a constant velocity, unless a non-zero net force acts upon it.
F = m a
For every action, there is an equal and opposite reaction.
I like turtles.
An object is moving with constant velocity. Which of the following statements must be true?
The net force on the object is zero.
A constant force is being applied in the direction of motion.
There are no forces acting on the object.
There is no frictional force acting on the object.
What is Newton's Second Law?
An object at rest stays at rest, and an object in motion stays in motion with a constant velocity, unless a non-zero net force acts upon it.
F = m a
For every action, there is an equal and opposite reaction.
I like turtles.
If a shopping cart’s mass is decreasing while a constant force is applied, what happens to its acceleration?
Acceleration goes up.
Acceleration goes down.
Acceleration stays the same.
I buy less groceries.
If you are pushing a table across the classroom and your friend jumps onto it, what will happen to the table’s acceleration?
Acceleration goes up.
Acceleration goes down.
Acceleration stays the same.
I have no friends.
What is Newton's Third Law?
An object at rest stays at rest, and an object in motion stays in motion with a constant velocity, unless a non-zero net force acts upon it.
F = m a
For every action, there is an equal and opposite reaction.
I like turtles.
