Newtons 2nd law states
Action/reaction
Inertia
F= m x a
None of the above
2
A car travels 70 km/hr North then turns and travels 70 km/hr Northeast. This is acceleration of
Force
Speed
Direction
Distance
3
A train with 33 cars (huge mass!) traveling at 88 mph takes about one mile to decelerate to a complete stop.
Newton's 1st law
Newtons law of conservation
Newton's 3rd law
Newton's 2nd law
4
A box has two forces acting on it: 16N to the left and 8N to the right. What are the net force and direction of motion?
8 N to the left
8 N to the right
24 N to the left
24 N to the right
5
Which law of motion applies: A backpack flies into the windshield when you suddenly stop the car.
Law 1
Law 2
Law 4
Law 3
6
A rocket moves upward as the exhaust pushes downward
Newtons 3rd law
Newtons 2nd law
All the Laws of Physics Ever!
Newtons 1st law
7
A child should use a seatbelt in a car to be safe. In an accident the child will
Continue forward until something stops them
Follow the law of inertia
Be stopped by the seatbelt
All of the above
8
What is acceleration?
Change in only direction
A change in force.
Change in speed &/or direction
All of the above
9
An identical force is applied to a bowling ball and a ping pong ball, what will happen?
The bowling ball moves faster.
They will never slow down.
The ping pong ball moves faster.
They both move at the same speed.
10
Newton's first law states:
Inertia
An object in motion keeps moving until something stops it
An object at rest stays still until something moves it
All of the above
11
Newton's third law states:
For each action there is an equal and opposite reaction
Figs are the best
An object in motion stays in motion.
The force on an object = its mass times acceleration
12
The sum of all forces acting on an object are called
Newtons laws
Products
Net forces
Total force tangents
13
Mass of object is 60 kg. Acceleration is 29 m/s
2
. How would you calculate the force acting on the object?
S = d/t
F/m = a
F/a = m
F = m x a
14
We just conducted a lab w/ a plate setting and a table cloth. It was an example of which law?
Law of Miss Sotnik's classroom
Law of mass & acceleration
Law of Inertia
Law of action / reaction
15
An acceleration (speed over time) graph shows a straight line then it dips down then it is straight again.
A car goes constant speed, slows down. Then constant speed.
A car drives up a hill and then straight again.
A car goes down a hill, stops, then starts again.
A car crashes into a snowbank
