Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity
Define acceleration
100
The natural force that causes things to fall towards earth.
What is Gravity?
100
a push or pull upon an object resulting from the objects interaction with another object
What is a force?
100
A quantity that has both magnitude and direction.
What is a vector?
100
States that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
What is Newton’s first law?
200
a force applied to an object at rest causes it to accelerate in the direction of the force
What causes acceleration
200
it comes from all the mass.
Where does gravity come from?
200
The force that opposes the motion of an object
What is Friction?
200
The starting point of the vector and the head or tip of a vector is the final, pointed end of the arrow.
What does the tail of a vector represent?
200
Is a quantitative description of the changes that a force can produce on the motion of a body.
What it Newton’s second law?
300
Formula of acceleration
300
F=G m1m2/r2
What is the equation for gravity?
300
A force that attracts any two objects with mass.We call it this because it always tries to pull masses together ,it never pushes them apart
What is Gravitational Force?
300
Displacement, velocity, acceleration, and force
What are some examples of vector quantities?
300
Wind, a ball being thrown, someone running, a fish swimming.
What are some examples of motion energy?
400
True: Accelerations are vector quantities
True or false: are accelerations vector quantities?
400
True: Gravity is a law and not a theory.
True or false: Gravity is a law not a theory.
400
Is the force that is transmitted through a string, rope, cable or wire when it is pulled tight by forces acting from opposites ends.
What is Tension Force
400
To add vector v to vector u Move vector v until it’s tail touches the head of u. The sum is the vector from the tail of u to the head of v
What is the head to tail rule?
400
The force on an object is equal to its mass times its acceleration.
What is the formula of Newton’s 2nd law?
500
Increasing speed, decreasing speed/ retardation, and changing direction
Types of acceleration
500
Gravitational, Electromagnetic, Weak nuclear, Strong nuclear.
What are the four types of gravitational forces?
500
The force of gravity on earth is always equal to the weight of the object as found by the equation:
What is Fgrav=m*g
500
Depict a vector by use of an arrow drawn to scale in a specific direction
How are vector diagrams used?
500
Rotary, Oscillating, linear, and reciprocating
4 types of motion
