In 1665 this British scientist concluded that the same unbalanced force that causes objects to fall to Earth was also the same force that kept the moon in orbit around the Earth.
Who is Sir Isaac Newton?
100
A push or a pull on an object.
What is force?
100
A pourch swing hanging from a pourch roof is an example of this type of force.
What is an example of a balanced force?
100
When you take an object to the moon this changes due to the low mass of the moon.
What is weight?
200
An object's change in position relative to a refrence point.
What is motion?
200
This is the measure of the gravitational force on an object.
What is weight?
200
The unit by which force is measured.
What is a Newton?
200
this is a combination of all the forces acting on an object
What is net force?
200
To produce a change in motion this type of force must be applied to an object.
What is an unbalanced force?
300
The speed of an object in a particular direction.
What is velocity?
300
The measure of the amount of matter in an object, this stays the same where ever you go in the universe.
What is mass?
300
When you take all the forces acting on an object and combined them you get this.
What is net force?
300
When forces are going in opposite directions of each other, you combine the forces by doing this.
What is subtracting the forces to get the net force?
300
The two factors that determine speed.
What is distance and time?
400
This is the rate that velocity changes over time. That object can change speed, direction or both to acheive this.
What is acceleration?
400
All objects in the universe attract each other through gravitational force. The size of the force depends on the masses of the objects and the distance between them.
What is the law of universal gravitation?
400
you must have this in order to have motion of an object.
What is an unbalanced force?
400
The force of gravity is greater on two objects if this is greater.
What is mass?
400
The roughness of an objects surface causes this force.
What is friction?
500
A cheetah running 27 m/s east is an example of this.
What is velocity
500
All matter is affected by this.
What is gravity?
500
An object at rest has this kind of force.
What is balanced forces?
500
Forces moving in the same direction on an object are combined by doing this.
What is add the forces to get net forces?
500
Your speed is not changing, but your direction is changing this is an example of this.
