Definitions Part II
100
This is defined as a push or a pull.
What is a force?
100
The type of force needed to keep an object still.
What is a balanced force?
100
A bowling ball moving down a lane toward the pins is an example of this type of type of motion.
What is linear motion?
100
These are ways we observe friction.
What is we can see it, feel it, and hear it?
100
This is the way an object feels.
What is surface texture?
200
This is defined as circular movement.
What is rotational motion?
200
The type of force needed to make an object move.
What is an unbalanced force.
200
A pendulum of a grandfather clock shows this type of motion.
What is oscillating motion.
200
Rough, smooth, and slippery are examples of this?
What is surface texture.
200
This is a force that resists movement.
What is friction?
300
This is defined as a repeated up and down movement.
What is reciprocating motion?
300
The name of the force that pulls objects toward the earth.
What is gravity.
300
A tire on a bicycle shows this type of motion.
What is rotational motion.
300
A mirror is an example of this type of surface texture.
What is smooth?
300
This is when two forces of equal strength act in opposite directions?
What is a balanced force?
400
This is what we say an object has when the forces on that object are balanced.
What is equilibrium?
400
When an object shows this, there is no change in motion.
What is equilibrium?
400
A piston in a cars engine shows this type of motion.
What is reciprocating motion?
400
The brakes on a car are an example of this.
What is an advantage of friction?
500
This is defined as the movement of an object from one place to another in a straight line.
What is linear motion?
500
These are all things force can do. (Four things)
What are make things move, slow things down, speed things up, and keep things still?
500
The Corkscrew roller coaster at Playland shows these two types of motion.
What is rotational and linear motion?
500
Hand lotion is an example of this type of surface texture?
What is slippery?
500
This is the definition of a swinging motion.
What is oscillating motion
