Motion
When do you say an object is in motion?
When it moves from one place to another.
What is the name of the science that studies motion?
Kinematics
How many types of motion exist?
Two
What is speed?
The time it takes an object to move a certain distance.
What is acceleration?
When an object's speed changes.
What is motion?
The change in position of an object.
What is distance?
Distance is the total length traveled by an object during its motion.
What is the name of the motion where there is no change of direction?
Rectilinear
What are the two things used to calculate speed?
Distance and time.
If an object is moving at a constant speed, is it accelerating?
No, because for acceleration to happen, speed needs to change.
What is a Point of Reference?
It is what you use to compare if an object is in motion or not.
What is displacement?
The distance between a moving object's initial position and final position.
What is the name of the motion where there is a constant change of direction?
Curvilinear.
What is velocity?
The time it takes an object to cover a distance and the direction.
If an object changes direction, is it accelerating?
Yes, because an object is always accelerating when changing direction.
What do you call an object that is not in motion?
An object that is not in motion is at rest.
What is trajectory?
The path an object takes when it is in motion.
What is the name of the motion where an object moves in a circle?
Circumference.
What are the units used to measure distance?
Meters, kilometers, miles.
What is the average speed of an object that is beginning to accelerate?
The speed of an object that is accelerating is always 0.
If you are inside a car, and all the objects around it are moving, what is the reference point?
You are the reference point.
If an object moves 5 meters North, 10 to the East, and 5 South, this is an example of...
Distance
What is the motion where an object moves horizontally and vertically?
Parabolic motion.
What are the units used to measure time?
Seconds, minutes, hours.
What do you need to be able to calculate acceleration?
To calculate acceleration, you need the initial speed and time, and the final speed and time.
