Motion
When an object moves from reference point to reference point, the object is in this.
What is motion?
Speed equals distance divided by this.
What is time?
The steepness of a line on a distance/time graph is called this.
What is slope?
When two forces act in the same direction, they do this.
What is they add together?
The force of gravity on a person or object on the surface of a planet is called this.
What is weight?
This is motion you can feel.
What is acceleration?
When you know both the speed and the direction of the object, you know this.
What is velocity?
In a distance versus time graph, this variable goes on the x axis.
What is time?
This tendency for an object to be lazy is called this.
One way to increase the acceleration of a wagon is by doing this.
What is decreasing mass or increasing force?
A car slowing down at a red light is an example of this type of acceleration.
What is deceleration?
Total distance divided by total time will give you this.
What is average speed?
A straight diagonal line on a distance versus time graph indicates a this.
What is a constant speed?
An object has more inertia if it has more this.
What is mass?
You can increase the momentum of an object by doing this.
If the speed of an object does not change, the object is traveling at this rate.
What is constant rate?
If a bicyclist travels 30 km in 2 hours, her average speed is this.
What is 15 km/h?
A horizontal line on a distance vs. time graph means this.
What is an object is a rest?
The force that one surface exerts on another when the two rub against each other is called this.
What is friction?
The amount of matter in an object is called this.
What is mass?
Changing direction is an example of a type of this.
What is acceleration?
What is velocity?
What is distance?
Air resistance is this type of force.
According to Newton's third law of motion, when a hammer exerts a force on a nail, the nail does this.
What is exerts an equal force back on the hammer?
