The acceleration includes what two factors.
What is distance and time?
What is the resistance to a change in motion called?
What is inertia
IF something is moving at a constant speed, is it balanced or unbalanced?
balanced
Which type of friction keeps things stuck in place?
static
Newton's Third Law of Motion states that the action and reaction must be
equal and opposite
If forces are equaled out, they are _________ forces.
Balanced
an object in motion stays in motion unless acted upon by an outside force, is an example of which law?
Newton's first law
A student lets a toy car roll four times down a ramp that is 1 m long. Each time the student covers the surface of the ramp with a different material. The student measures the time it takes the car to roll down the ramp and records the info. Each trial has a different time. What conclusion can you draw about the ramp?
Different amounts of friction
what type of friction slows down moving objects?
kinetic
If you put a notecard on a cup, and a penny on top of the notecard and flick the card so the penny falls in the cup, which force is acting on the penny so it falls down?
gravity
One object pushing on another will always receive a push in return. True or false.
True
What happens when a rocket launches to make it an example of Newton's Third Law?
As the fuel burns, gases push against the rocket, moving it upward.
If a box is being pushed with a force of 5 N to the right and also being pushed, in the opposite direction with a force of 12 N, would you add or subtract to find the net force?
subtract
push or pull
what is a force
If someone is pushing a box with 15 Newtons of force to the right, and another person is pulling the box with 5 N of force, what is the net force?
20 N to the right
What causes a ball that has been kicked across the ground to stop?
Friction
Objects with more mass are ______ to set in motion.
harder
If two rocks with different masses are rolling down a hill, will the bigger rock, or smaller rock take more force to stop?
the bigger rock
causes an object to move
unbalanced force
net force
what is the total force acting on an object called
According to Newton’s Second Law, if the force increased but the mass remained the same, what happened?
The objects acceleration increased.
dribbling a basketball is an example of which law?
What is Newton's third law

What is gravity
used to determine that motion has taken place
reference point
