SPEED
What is the distance/time?
This is the equation for speed.
What is push or pull?
The definition for force
What is newton's second law of motion
The acceleleration of a object depends on the mass, and on the magnitude of the force acting on it
What is motion?
The distance from one object to another is changing
what is newtons frist law of motion?
Objects in motion will stay in motion while an object at rest tends to stay at rest unless acted upon by an unbalanced force.
The average speed of a bicycle that traveled a total of 100 meters in 10 minutes can also be said
1o meters per minute
What is net force?
The sum of all force acting on an object.
If a car turns a corner at a constant speed, is it accelerating?
Yes
What is acceleration?
A change is a moving objects speed or direction
Is a book lying on a table an example of newtons frist, second, or third law of motion
Thrid
How can you calculate the average speed?
By diving the total distance by the total time.
What is static friction?
This friction acts on an object that is not moving
To determine the acceleration what do you have to calculate?
The change in speed per unit of time
What is the force the pull two objects towards one another, generally downward?
Gravity
What is force = mass X acceleration?
The equation for newtons second law
What is velocity?
Speed with direction
What is weight?
This is the force of gravity on an objects mass
The two ways to graph acceleration and with distance vs. time and?
Speed vs time
What is an unbalanced force?
The type that causes an object to change its motion
What newtons law states that for every action force there is an equal and opposite reaction force?
Newtons law of action-reaction
What is the difference between speed and velocity
Speed is time and distance. velocity is time and distance with directions.
M X A=?
force
What is increasing speed, decreasing speed, and changing direction?
Three ways you can accelerate
What is an objects tendency to resist any change in its motion
Inertia
The more_____ an object has, the harder it is to stop
Momentum
