Force and Motion
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?
Newton's First Law of Motion states that an objects...
motion will remain constant unless acted upon by an outside force.
This is the force that pulls things to the center of the earth.
What is gravity?
50m/s What's the units?
m/s (meters/second)
What is Newton's First Law of Motion?
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.
What is the formula to calculate speed?
What is distance divided by time?
What formula would you used to solve for force?
mass x acceleration
These two things determine the amount of gravity between two objects.
What is the distance and mass of the objects?
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 is the unit for force?
Newtons (N)
A change in a moving object's speed or direction is..
What is Acceleration?
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?
When an object wants to keep motion or sitting still...
What is Inertia
Name two common units for mass.
Grams and Kilograms
Why do people jerk forward when a driver pushes the brakes suddenly?
What is inertia?
When graphing a car's speed, what goes on the X and Y Axis?
X-axis = time
Y-axis = distance
A force that resists movement
What is friction?
This friction is when a car slams on its brakes and skids across the road.
What is sliding friction?
Name a noncontact force.
Gravitational Force
50 N right and 60 N left will result in.
10 N left
A combined force that causes something to move is a balanced or unbalanced force?
What is an Unbalanced Forces?
What is Newton's Third Law of Motion?
the Law of Motion that states for every action there is an equal and opposite reaction....
Type of Friction when something is not moving
What is static friction?
What is the largest organ in the human body?
The skin
