Terms
The location of an object at a specific time.
What is the position?
An object at rest stays at rest, and an object in motion remains in motion at a constant speed and in a straight line unless acted upon by an unbalanced, external force.
An interaction between two objects that results in a push or pull.
What is a force?
What is the magnitude?
A 50 kg wagon accelerated at a constant force of 4m/s^2, which needed this many newtons/force to be applied.
What is 200 Newtons? (50kg x 4m/s^2)
The change in position of an object over time.
What is motion?
If object A exerts a force on object B, object B simultaneously exerts an equal force in the opposite direction on object A.
Equal and opposite forces acting on an object, resulting in 0 net force.
What is a balanced force?
What is speed?
A 10 kg box is pushed by a 50N force. This is the acceleration.
What is 5m/s^2?
The change in an object's position from the beginning point to ending point.
What is the displacement?
the net force acting on an object is directly proportional to its acceleration and inversely proportional to its mass
Magnetic ___, Electric Static, Buoyant ___, and Nuclear ___(s)
What are examples of forces?
The rate of which an object changes velocity. (ie. speeding up, slowing down)
What is acceleration?
The standard unit for force, equalling 1 kg x m/s^2.
What is a Newton?
A quantity with both magnitude and direction.
What is a vector?
A car requires more force to achieve the same acceleration as a bicycle.
What is an example of Newton's 2nd Law?
Unequal, non-zero ___s that result in movement, acceleration, or displacement.
What is an unbalanced force?
The rate of change of an object's position in respect to time.
What is velocity?
If an equal force pushes a pencil and a textbook, this one will have more acceleration.
What is the pencil?
A fixed, stationary point to determine the position, distance, or motion of another object.
A swimmer pushes backwards on the water, and the water pushes the swimmer forward.
What is an example of Newton's 3rd Law?
A vector sum of all individual forces acting on an object.
What is the net force?
A single quantity described by one single, numerical value.
What is a scalar quantity?
What is are the three equations for finding force, mass, and acceleration?
What is F=MA, A=f/M, m= f/A
