Distance & Speed
This is calculated by dividing distance by time
What is speed?
On a distance-time graph, the x-axis represents this.
What is time?
A push or pull is called this.
What is force?
This is the force that pulls objects toward Earth.
What is gravity?
A scientific law describes this.
What is what happens in nature?
An object travels 60 meters in 5 seconds. Its speed is _____.
What is 12 m/s?
On a distance-time graph, the y-axis represents this.
What is distance?
Friction is best described as this type of force.
What is a contact force?
This depends on gravitational pull and can change on the Moon.
What is weight?
A scientific theory explains this.
What is why or how something happens?
If speed stays the same, motion is described as this.
What is constant (or uniform) motion?
A straight, diagonal line on a distance-time graph shows this type of motion.
What is constant speed?
If forces are equal and opposite, they are called this.
What are balanced forces?
This is the amount of matter in an object and does not change with location.
What is mass?
This is NOT just a guess but a well-supported explanation.
What is a scientific theory?
If distance increases but time stays the same, speed will do this.
What is increase?
The steepness of a graph line is called this.
What is slope?
If the net force is not zero, forces are this.
What are unbalanced forces?
If mass increases, gravitational force will do this.
What is increase?
The Law of Gravity is an example of this.
What is a scientific law?
This formula is used to calculate speed.
What is Speed = Distance ÷ Time?
A flat horizontal line on a distance-time graph means the object is doing this.
What is not moving (at rest)?
Unbalanced forces can change an object’s speed, direction, or this.
What is both (speed and direction)?
As distance between two objects increases, gravitational force will do this.
What is decrease?
Both scientific laws and theories must be supported by this.
What is evidence?
