Force
What do balanced forces equal?
0
What will happen when two balls with the same speed ram into each other? What will happen to the momentum? Will it be conserved?
The momentum will be conserved
What is it called when the path of something thrown is curved
Trajectory
What is it called when two objects slide against one another?
Friction
What is the product of the mass and velocity of an object.
Hint; its one of the catagories
Momentum
What needs the most force to push/pull 100 kg rock or 101 kg of feathers?
Feathers
Which one of Newton's laws explains inertia?
The First
Where would one aim to shoot a bow at the center of a target?
Slightly above the target
Name a factor that affects the friction of something pulled across a wooden floor
One of these
Surface Area, forces pressing them together,
What is the natural tendency of objects in motion to stay in motion and objects at rest to stay at rest
Inertia
True or false, Newton's Second Law states that for every action there is an equal and opposite reaction.
True
What has the least inertia?
1kg rock, 2kg cat, 10 gram toy car, or 10kg Tire
10 gram toy car
Projectile
What would you expect the friction of pulling one block to do when you add another block
double
What does Newton's First Law state
states that an object at rest will remain at rest
Find the Force
A ball (10kg) is rolling down a hill at (9.8m/s/s) what is the force?
98N
What is inertia correlated to
Mass and acceleration
Why is trajectory present
gravity
What type of friction occurs when you hit the brakes on a bicycle?
Sliding Friction
What is Newton's Second Law
It states the greater the force applied to an object, the greater its acceleration, and the more massive an object is, the more force is required to produce the same acceleration.
Find the force
A 18-Wheeler (20000kg) is going down the highway and accelerating at a speed of 5m/s/s, what is the force?
100000N
If an astronaut throws a ball in space what will happen?
The speed will stay the same until acted upon
Why would a ball that was thrown fall in a curved pattern
Trajectory
Name the 4 types of friction in order of least to greatest strength
Rolling, Sliding, Fluid, Static
What is Newton's Third Law
That for every action, there is an equal and opposite reaction.
