This is defined as a measurement of speed and direction.
What is Velocity?
If an object’s acceleration is not changing, then this acting on it is equal to zero.
What is the net force?
This is the force that pulls objects toward the earth.
What is gravity?
This is how acceleration is defined.
What is a change in velocity?
What is a magnet?
What is a material that can pull certain types of metal toward itself?
An object at rest will remain at rest and an object in motion will stay in motion unless acted upon by an unbalanced force is what law?
What is Newton's 1st law?
This is defined as the flow of charge /electrons in a complete circuit and is measured in amps.
What is current?
If an object’s acceleration is changing, then it is being acted upon by these forces.
What are unbalanced forces?
When the net force on an object is 0, the forces acting on it are called this.
What is balanced?
A positive acceleration means this.
What is an object is speeding up?
Magnetic Field is described as this.
What is the magnetic forces between the two poles of a magnet?
This is how you find out the speed of a car.
What is dividing the distance by the time it took to travel a specific distance?
These are the unit of force.
What are Newtons?
If an object is traveling, unbalanced forces can change these two things.
What are the speed or direction an object is traveling?
Balanced forces are this in size and this in direction.
What are equal in size and opposite in direction?
A change in direction can be called this.
What is an acceleration?
Magnets strongly attract objects that contain any of these 4 things.
What are iron, steel, nickel, or cobalt?
This is defined as what makes current flow.
What is Voltage?
Speed is a measurement of this.
What is the rate of motion?
If the net force acting on an object is this, then the object is not accelerating
A negative force means this.
What is the force is acting in the opposite direction from the direction you made positive?
If an object is slowing down, it means this.
What is negative acceleration?
Magnetic strength is based on this.
What is the material that the object is made of, not the distance between them. The stronger the magnet, the greater the attraction or repulsion?
Speed is this type of quantity, so direction does not matter when finding speed
What is scalar?
This is a straight-line length between a starting point and ending point.
What is displacement?
If an object is not accelerating, it may be these two options.
What are a constant velocity or stationary?
If the forces acting on an object are unbalanced, the object will do this.
What is accelerate?
If you know the force acting upon an object and its mass, you can solve for this.
What is acceleration?
The Earth has a electric field because of this reason.
What is the source of the magnetic field that surrounds Earth is the motion of its core, which is composed mostly of iron and nickel?
Velocity is this type of quantity, so direction does matter when finding velocity.
What is vector?
Applied force is defined as this.
What is any force that is transferred to an object by a person or object?
If you need to figure out Velocity, you do this.
What is divide the displacement of an object by the time it took the object to travel from the starting point to the ending point?
If you know the force acting upon an object and its acceleration, you can solve for this.
What is its mass?
You can the velocity of a dropped object by doing this.
What is by multiplying the acceleration due to gravity by the number of seconds the object has been falling?
This is why like ends of magnets repel while opposite poles attract.
As with electric charges, opposite poles of a magnet attract and like poles—or poles that are the same—repel, or push each other away. Every magnet has both a north pole and a south pole.
This is a substance in which electrical charge move easily from atom to atom with the application of voltage. Copper, steel, gold, aluminum, and brass are also good examples.
What is an electrical conductor?
