What is the mathematical formula for acceleration
F= m x a
An object in motion stays in motion, an object at rest stays at rest until acted on by an outside force.
Newton's 1st Law
For every action, there is an equal and ______ reaction.
Opposite
What Law is Action / Reaction?
Newton's 3rd Law
A baseball bat hits a ball. Besides flying through the air, what does the ball do?
Hits the bat with equal and opposite force
When an object is not in motion it has an ________________ force.
Balanced
This is the Law of Inertia
Newtons First law
This law explains why a balloon flies around the room when you let it go without tying it.
Newton's 3rd Law
The term used for the resistance of an object to changes in its state of motion, as described in Newton’s First Law.
Inertia
When an object is in motion it has _______________ forces.
Unbalanced?
According to Newton’s Second Law, increasing the force applied to a mass has this result.
Increases acceleration of the object
A box is being pushed to the right across the floor. What force is acting on it on the floor?
Friction
The unit of force is this.
Newton
In Newton's Second Law, if mass is constant and force increases, this must also increase.
Acceleration
Mass has this unit.
kg, kilogram
What is the Net Force?
What is 0?
A bowling ball collides with a set of bowling pins (at rest) with a force of 15N. What is the force the pins exert on the bowling ball?
15N
What is the Net Force?
What is 50?
What force stops a ball that is thrown in the air from flying up forever?
Gravity
A force of 20N acts upon a 5 kg block. Calculate the acceleration of the object.
4m/s2
An object at rest has this velocity.
Zero
If you want to increase the acceleration of a baseball when you throw it, what must you increase to make this happen?
Force
A net force of zero results in this type of motion, according to Newton’s First Law.
Constant velocity or no motion
If a heavier object needs more force to move than a lighter one, you’re seeing this law in action.
Newton’s Second Law (F = ma)
What is velocity?
How fast something(an object) is moving in a given direction.
