Force and Motion 1
What is a force?
A push or a pull
This is a measure of how fast something moves through a distance in a given amount of time.
What is speed?
50m/s What's the units?
m/s (meters/second)
This law explains why when you kick a soccer ball it goes flying and you feel the force on your foot in the opposite direction.
What is Newton's Third law of motion?
What is the unit for force?
Newtons (N)
What is Newton's First Law of Motion?
What is if an object is at rest it will stay at rest, if an object is in motion it will stay in motion, until acted upon by an outside force.
A force that resists movement
What is friction?
What formula would you used to solve for force?
mass x acceleration
What is Newton's Third Law of Motion?
the Law of Motion that states for every action there is an equal and opposite reaction....
What happens if there is no force acting upon an object?
It will continue to move at the same speed in the same direction.
What would happen if you threw a ball in the air in outer space?
It will travel in a straight line forever
The sum of forces on an object
What is net force?
Name two common SI units for mass.
Grams and Kilograms
Newton's First Law of Motion states that an objects...
motion will remain constant unless acted upon by an outside force.
An object with more mass takes longer to stop. What is this an example of?
What is a Momentum?
Why do people jerk forward when a driver pushes the brakes suddenly?
What is inertia?
50 N right and 60 N left will result in.
10 N left
A change in a moving object's speed or direction is..
What is Acceleration?
When graphing a car's speed, what is the independent and dependent variable?
Independent = time
Dependent = distance
This is the force that pulls things to the center of the earth.
What is gravity?
What is the formula to calculate speed?
What is distance divided by time?
A 50 kg rock accelerates down a hill at 10 m/s2. What is the force of the rock?
What is 500N?
When an object wants to keep motion or sitting still...
What is Inertia
A combined force that causes something to move...
What is an Unbalanced Forces?
F=ma is the basis of which Law of Motion?
What is the 2nd Law of Motion?
