Move It, Move It
This information pair is needed to calculate an object's average speed.
What is distance and time?
When a toy car slows down after being pushed, this force is responsible.
What is friction?
A horizontal line on a distance vs. time graph means this.
What is no motion?
This term means “an object’s location compared to another object.”
What is position?
If the net force on an object is zero, the forces are called this.
What are balanced forces?
If the distance between an object and a reference point does not change, this can be inferred.
What is the object is not moving?
If the net force on an object is not zero, the forces are described this way.
What is unbalanced?
A steep line on a distance-time graph means this about speed.
What is fast speed?
If your distance from a reference point changes, then this is happening.
What is motion?
If forces are unbalanced, this happens to the object.
What is it accelerates?
On Elena’s jogging chart, her speed between 5 and 10 minutes does this.
What is stays the same (constant speed)?
When a sneaker is pulled left with a spring scale, friction acts in this direction.
What is to the right?
If a line on a distance-time graph is straight but diagonal, the object is moving at this kind of speed.
What is constant speed?
A runner travels 40 m in 10 s. What is her speed?
What is 4 m/s?
Name one force that opposes motion when two surfaces rub.
What is friction?
A straight diagonal line on a distance–time graph means this type of speed.
What is constant speed?
When a basketball hits the pavement, the forces between the ball and the ground are best described by this Newton’s Law idea.
What is equal force in opposite directions?
A curved line that gets steeper over time represents this.
What is speeding up/ acceleration?
Two bicyclists pass each other. One says the other is moving faster. What evidence do they need to prove it?
What is distance and time?
A book sits on a table. Gravity pulls down, and this force pushes up.
What is the normal force?
Alyssa runs 150 meters in 25 seconds. What is her speed?
What is 6 m/s?
Draw this scenario: A car travels in a pattern: constant speed → stops → speeds up. Describe the graph’s shape.
What is diagonal line --> flat line --> steeper diagonal line?
On a distance-time graph, how can you tell which of two objects is faster?
What is the steeper slope belongs to the faster object?
An object is accelerating. What must be changing?
What is its speed or direction?
Two runners start at the same time. Runner A has a straight line; Runner B has a curved line. What does that mean?
What is A= constant speed, B =changing speed?
