Newton's second laws
What another name for Newton's 2nd law
Law of momentum/Law of force and acceleration
A push or a pull.
What is a force?
The unit of force named after its namesake.
What is a Newton?
The momentum value of a 3000kg bus moving 10 m/s.
What is 30000 kgm/s?
The reaction force for the ground rubs me.
What is I rub the ground?
Describes the type of movement an object has with no outside forces acting on it other than gravitation.
What is Free Fall? OR What is the Acceleration due to gravity?
When the net force on a mass equals zero.
What is a balanced system?
For every action there is an equal and opposite reaction.
What is Newton's 3rd Law?
The moon lacks this force which allows it to constantly orbit the earth.
What is friction?
What is drag?
The cause for a mass to accelerate or change direction.
What is an unbalanced force?
The law that describes the net rate of change of momentum acting on an object directed in one direction.
What is Newton's 2nd Law?
An object at rest will remain at rest and an object in motion will continue moving at a constant velocity unless acted upon by a net force
What is Newton's First Law?
The force provided by the elevator motor to move a 600N person and the 9000N elevator upwards at 10m/s.
What is 9600N?
The type of motion of a free falling object when the weight force equals that of the drag force.
What is Terminal Velocity?
Would an unbalanced force affect Newton's 2nd law
No, because an unbalanced for is one of the things that his 2nd Law defines
The force which always rubs you the wrong way.
What is friction?
A horse moves a cart because THIS reaction force of the horse pushing against the ground is greater than the reaction pair of forces on the wheels of the cart.
What is the ground pushing the horse?
The reason why deflecting an asteroid away from the earth is almost impossible?
What is inertia? OR What is a moving mass?
What is acceleration?
The force that attracts masses towards each other.
What is Gravitation?
The term used for the sum of all the forces acting an an object.
What is the net force?
The most commonly stated force provided by a table or any surface that preventing an object from falling to the center of the earth?
What is Force Normal?
The type of movement a mass has when the net force equals zero.
What is constant motion? OR What is constant velocity?
The COMMON term given to an applied force by a jet engine.
What is thrust?
