What is an unbalanced force?
Unbalanced forces happen when forces are not equal in magnitude and/or act in the same instead of opposite directions.
How are speed and velocity different?
Speed is only how fast an object is moving. Velocity is how fast an object is moving and it's direction.
What is Newton's Third Law?
The third law states that for every action, there is an equal and opposite reaction.
Can you define speed?
A measure of the distance an object travels in a certain amount of time.
What was our coin drop experiment proving?
Newton's First Law
Can you give an example of unbalanced forces?
Answers can vary
What is Newton's Second Law?
The greater the mass of an object, the more force it will take to accelerate the object.
If you push into the wall, it pushes back into you with the same force. True or False?
True
What is the equation for speed?
Speed = Distance / Time
What was our mass-car experiment proving?
Newton's Second Law
What is Newton's First Law?
The first law says that an object at rest tends to stay at rest, and an object in motion tends to stay in motion, with the same direction and speed.
What is the equation for force?
Force = Mass x Acceleration
When a bird flaps its wings downwards, what is the reaction force?
The air lifts the bird up so it flies.
If a car drives 500 miles and it takes 10 hours, what is it's speed?
50 Miles per Hour
If a plane flies 200 miles in 2 hours, what is it's speed?
100 Miles per Hour
What is friction?
A force that slows or stops motion between two surfaces that are touching.
What is the definition for acceleration?
The measurement of change in an object's velocity.
A rocket pushes gas downwards. What is it's opposite reaction?
It starts lifting into the air. It goes up.
If a car drives 300 miles in 15 hours, what is it's speed?
20 Miles per Hour
A force is an action that changes or maintains the motion of a body or object.
Simply stated, a force is a push or a pull.
What is inertia?
The tendency of an object to resist changes in motion.
There are two suitcases, one weighs 10 kg and one weighs 20 kg. If they both move 100 meters, which one required more force?
The 20 kg suitcase
A fish swims by pushing water back with it's fins. What is the reaction force?
The water pushes the fish forward.

38 Miles per Hour
What forces are acting on the plane?
Gravity, Thrust, air resistance, lift
