What is another name for Newton's Third Law of Motion
The law of action and reaction.
A book sitting on a shelf is an example of what type of force
Balanced forces
What is net force?
The sum of all the forces acting on an object.
An object is released in space far from any other objects. What will happen to it if it has an initial momentum?
what is motion.
What are the units for force in the metric system.
What is newtons.
Does a rocket push on the Earth or on something else to propel itself into space
A rocket pushes on the gases it expels
If a car is moving at a constant speed, are the forces acting on it balanced or unbalanced?
Balanced.
What is the unit of force and therefore net force?
Newton.
A coin falls into a cup when the coin's supporting index card is flicked away What principle from Newton's first law explains why the coin falls straight down?
An unbalanced force
What is the relationship between force, mass, and acceleration in Newton's Second Law?
Acceleration is directly proportional to the net force.
What does Newton's Third Law state about forces
For every action there is an equal and opposite reaction.
In a tug-of-war if both teams pull with the exact same force in opposite directions the forces are
Balanced not move.
What happens when the net force on an object is zero?
what is Balanced forces?

An unbalanced force
If you push a bowling ball and a tennis ball with the same amount of force.Which will accelerate more?
What is Tennis Ball?
If you push on a wall what is the reaction to that action
The wall pushes back on you with an equal and opposite force.
What happens to an object when only unbalanced forces act on it.
It will accelerate (speed up).
Two people push a box Person A pushes with 20 N to the right, and Person B pushes with 15 N to the left. What is the net force?
20-15=5N
If a car requires 1000 N of force to maintain a constant velocity what is the magnitude of the frictional force acting on the car
What happens to the acceleration of an object if its mass is doubled, but the applied force remains the same?
The acceleration will be halfed.
