100
What type of force is used when you brush your teeth?
Push and Pull
100
Explain how different types of surfaces can change the speed and direction of objects. Remember our experiment with the bubble wrap, wax paper, and cloth.
A smooth surface creates less friction causing objects to move faster and a rough or bumpy surface will cause more friction making objects move more slowly.
100
How can force change the speed and direction of an object?
When a force is applied to an object, it causes it to move. The harder the force, the faster the speed. A force can make an object move in different directions. Example: If you push a toy car is will move forward but if you pull on it, it will move in the opposite direction.
100
What is a plane surface or a ramp that is set at an angle to a horizontal surface.
Inclined Plane
100
Define the word Distance
The amount of space between two points.
200
Name the force used when you pick up a a bowling ball.
Pull
200
If you throw a ball in the air, it would fall back down to the ground. Explain why.
Earth's gravity is pulling the object (ball) toward Earth.
200
Sir Isaac Newton said that an object at rest will remain at rest and an object in motion will likely stay in ___________.
Motion
200
What is the act of moving or changing place or position.
Direction
200
Define the word Direction
The path that something moves or travels.
300
What type of force is used if you ride a skateboard?
Push
300
What is friction and give one example.
The act of rubbing two objects together
300
What is the natural force that attracts any two objects with mass toward each other.
Gravity
300
What is the word that means to press against with force in order to move it away?
Push
300
Define the word Friction
The act of rubbing two objects together.
400
When playing tug of war, what type of force is used?
Pull
400
If a baseball and paperclip were held at the same height and dropped to the floor, which one would land first and explain why?
They would land on the ground at the same time because Earth's gravitational pull is the same on all objects regardless of mass.
400
How does gravity affect objects on or near Earth?
Gravity pulls on objects on or near Earth causing them to fall to Earth until the two objects are connected. Remember the egg drop experiment?
400
What is a simple device for altering the magnitude or direction of a force.
Simple Machine
400
Define the word Speed
The rate of motion or how fast an object moves.
500
What are three types of forces?
Push, Pull, Push and Pull
500
What type of surface would be best to ride a skateboard and explain why.
A smooth surface would be best because it create less friction. Imagine riding a skateboard on a gravel road. Would it be easier or harder?
500
Describe Sir Isaac Newton's first law of motion.
An object will stay in motion unless there is an unbalanced force.
500
What is the natural force that attracts any two objects with mass toward each other.
Gravity
500
Define the word Gravity
The natural force that attracts any two objects with mass toward each other.
