Forses And Motian Flashcards
Reference point
A non moving object that is used to measure motion it references a moving object
Weight
A measurement of a gravitational force exerted on an object it’s value can change with the location in the universe
Mass
A measure of the amount of matter in an object
Gravity
A force of attraction between an object due to there masses
Friction
A force that opposes motion between two surfaces that are in contact
Force
A push or a pull exerted on an object in order to change the motion of an object
Acceleration
The rate of which velocity changes over time an object accelerates if its speed or direction or both changes
Velocity
The speed of an object in a particular direction
Speed
The distance traveled by an object divided by the time it took
Motion
When an object changes position over time relative to a reference point it is In motion
What affects gravitational pull
Distance and mass
How do u calculate average acceleration
Time it takes to change velocity
When is friction helpful
When your driving because without friction wheels could not push of the ground and move and you would not be able to stop your car with the breaks
How do u calculate net force for opposing forces? Combined forces?
Large force - small force = net force
How do unbalanced forces affect moving objects? Non moving objects ?
Changes it’s speed direction or both
How are speed and velocity similar? Different?
Both determine distance and time but velocity determines direction
How do u calculate speed
Time
What’s the difference between weight and mass
Weight is the amount of gravitational pull fords and mass is the amount of matter in an object
What causes friction
When two surface come in contact with each other
Or a rough surface
What are the two factors involved in acceleration
Velocity + time
What does the universal law of gravity state
All objects in the universe attract each other through gravitational force. The size of force depends on the masses of the objects and the distance between them
How do u reduce friction
Use lubricants
Make the surfaces smoother
SI unit for force
Newton
Unbalanced force
Result in Motion when a force is unequal
