The energy of motion is known as:
Kinetic Energy
a push or a pull is known as:
force
The net force of two people of equal force pulling on opposite ends of a rope
zero (0)
Graph used to record motion:
Distance Time Graph
the force responsible for a balloon sticking to a wall
electrical force
How would the line appear on a distance time graph if a vehicle traveled at a constant rate of speed, slowed down, then came to a stop?
It would move diagonally then a slight curve for a short distance before going horizontal representing the stop or at rest time
What forces impact a leave falling from a tree
gravity and air resistance
which is a contact force: a leaf falling from a tree or a book sliding across a table
book sliding across a table
what is the difference between a contact and non-contact force
contact forces require objects to physically touch and non-contact forces are a push or pull that requires no physical touch
what two things impact the gravitational pull of an item
distance and mass
a ball accelerating down a hill is an example of balanced or unbalanced forces
unbalanced
block A has a net force of 0 and block B has a net force of 4 - which block will move and why?
Block B because it has unbalanced force
On an airplane (lift above, weight below, drag at tail, and thrust at front) what would cause the airplane to descend toward the ground?
If the weight were more than the lift
explain the difference between mass and weight
mass is the amount of matter in an object and stays constant while weight the force of gravity on an object and changes depending on the location in the universe
Explain the importance of a reference point
To gauge the movement/motion of another object
What is Newton's First Law of Motion?
An object at rest stays at rest, an object in motion stays in motion unless acted on by another force.
What is Newton's First Law known as? The Law of
Law of Inertia
Newton's second law of motion describes acceleration as force divided by
mass
A duck flies 60 meters in 10 seconds, what is the duck's speed?
6 m/s
When you slide a box across a floor what force must your push be stronger than
frictional force
name the contact forces
friction, air resistance, normal force, and applied force
name the non-contact forces
magnetism, electrical force, gravitational force
what has a greater inertia a bowling ball or a baseball and why?
bowling ball because it has a greater mass
why do you not completely sink into the ground when you push on it as you walk?
because the ground pushing back with an equal force
all objects are attracted to one another and mass and distance determine the strength of the gravitational attraction
