who was the first scientist to study the falling objects of gravity in the 1600s
100
Yes
Is there high tides on both sides on the Earth
200
Momentum
Can be used to find the force needed to stop a moving object.
200
Speed
What is a measure of how fast an object is moving
200
electric current
What is a flow of electric charge in a material
200
1st
What is the law of motion that states an object at rest remains at rest, and an object in motion remains at constant speed
200
3rd Law of Motion
What is the Law of motion that states When a force is applied to an object, the object exerts an equal force in the opposite direction
300
Inertia
What is the tendency of an object to remain at rest or in constant motion unless a force acts on it
300
Compound machine, washer
What is a machine that contains one or more simple machines, give an example.
300
Magnetic domain
What is a large number of atoms with their magnetic fields pointing in the same direction
300
inertia
What is the tendency of an object to remain at rest or in constant motion unless a force acts on it.
300
The screw
What is an inclined plane wrapped in a spiral
400
Velocity
What is the speed of an object in a particular direction.
400
effort force
The applied force is called
400
electric motor
What is a device that changes electrical energy to kinetic energy.
400
acceleration= force dived by mass
What is the equation for the second law of motion
400
Speed
What is the following equation used for average speed=distance over time
500
Third-Class Lever
What has a fulcrum at one end, the load at the other, and effort force in the middle
500
generator
What is a device that changes mechanical energy into electrical energy
500
Second Law
What is the law of motion that states The acceleration of an object depends on the mass of the object and the size of the net force applied
500
Static Friction
What is resists the motion of an object just as it begins to move
