Acceleration
The unit of measure for an acceleration.
m/s2
A car is traveling 20 m/s and then 2 seconds later it is moving 10 m/s. This would be its acceleration.
What is -5 m/s2?
These three laws were discovered and attributed to the work of Sir Isaac Newton when he observed???
An apple falling from a tree.
Which object is accelerating more a fly or a train moving slow?
A fly
The pandemic that forced Newton to the countryside where he developed the Laws of Motion.
The Bubonic Plague
To accelerate a body in motion it may speed up, slow down, or ...
change direction
A 5 kg block is shoved at 3 m/s. The force of the block would be . . .
15 kg * m/s2 or 15 N
Newton's 1st Law of Motion is also known as
Law of Inertia
Define Inertia
The tendency of an object to resist a change in motion.
The Law of Universal gravitation allows someone to calculate this between any two objects in the universe.
Force
What force accelerates objects in a vertical motion or downward?
gravity
The mass of a metal plate falling at 7 m/s2 moving with a force of 9.8 N is?
1.4 Kg
The Law of force pairs is known as
Newton's 3rd Law of Motion
A push or a pull is
force
Inertia and momentum share a single item that is defined as the amount of matter in an object.
mass
What happens to the acceleration of an object with a large mass?
It decreases acceleration / Slows down
The mass of a ball that is struck by a force of 250 N with a bat accelerating at +10 m/s2.
25 kg
Newton's 2nd Law of Motion's uses this formula to calculate force.
mass multiplied by acceleration
What forces are acting to balance the Balanced Rock in Idaho?
Normal force and Gravity / weight
The measure of gravity on any mass.
weight
How do test with crash dummies, seat belts, and air bags illustrate?
It illustrates Newton's 1st law of motion by stopping inertia in the dummies.
The acceleration of a particle with a mass of 0.06 kg undergoing a force of 300 N.
5,000 m/s2
What would happen to the moon if Earth stopped exerting the force of gravity on it?
The moon will fly away.
How is net force determined?
By adding all the forces acting on an object. If the forces are moving in the same direction you will add, if the forces are moving in opposite direction you will subtract and give the direction of the biggest.
The Law considered Newton's greatest accomplishment.
