Speed & Motion
This term describes how fast an object moves over a certain amount of time.
What is speed?
On a distance–time graph, this variable is placed on the horizontal (x) axis.
What is time?
A push or a pull acting on an object is known as this.
What is a force?
This scientific skill allows researchers to design investigations and solve problems in new ways.
What is creativity?
An object that does not change its position over time is described as being this.
What is at rest?
A cyclist travels 30 kilometers in 3 hours. This value describes the cyclist’s average movement rate.
What is 10 km/h?
A flat, horizontal line on a distance–time graph tells us the object is doing this.
What is not moving / at rest?
This type of force causes an object to change speed, direction, or start moving.
What is an unbalanced force?
A scientist who studies how things move and interact uses this branch of science.
What is physics?
If the net force on an object is zero, the object will do this.
What is stay at rest or move at constant speed?
If two runners travel the same distance, the one who finishes first has more of this property.
What is greater speed?
If an object’s graph slopes downward, it means the object is moving in this way.
What is returning toward the starting point?
This force keeps planets and moons moving in curved paths around larger objects.
What is gravity?
When scientists use tools like graphs, models, or videos to explain their ideas, they are doing this.
What is communicating scientific information?
Two objects move the same distance, but one takes less time. The object that took less time is this.
What is faster?
On a distance–time graph, a straight line that slopes upward shows this type of motion.
What is constant speed?
Two objects travel for 5 seconds. The one with the steeper graph traveled this way.
What is faster?
When opposing forces on an object are equal, the object will do this.
What is stay at rest or move at constant speed?
Scientists use evidence and observations to answer questions. This process is called this.
What is scientific investigation?
A distance–time graph with a steeper line than another graph shows this comparison.
What is greater speed?
When a distance–time graph becomes steeper, this characteristic of motion is increasing.
What is speed?
Speed can be calculated from a distance–time graph by finding this mathematical value.
What is slope?
Increasing this will make a shopping cart accelerate more quickly.
What is the applied force?
When scientists test ideas by collecting data and making conclusions, they are doing this.
What is conducting an experiment?
An object speeds up, slows down, or changes direction only when this occurs.
What is an unbalanced force acting on the object?
