Motion
The distance in a given direction from a fixed reference point.
What is Displacement?
A rubber band being stretched is experiencing this type of force.
What is Tension Force?
The unit of Work.
What are Joules?
A scalar quantity defined as the distance travelled over the time taken, represented by the symbol v.
What is Speed?
Combination of all forces acting on an object.
What is the Resultant or Net Force?
Work done is represented by the area under this type of graph.
What is a force—displacement graph or a distance graph?
The gradient of velocity.
What is acceleration?
This famous physicist theorized the three laws of motion. Describe one of the three.
Who is Isaac Newton? Inertia (1), F=ma (2), or Equal and Opposite Forces (3).
The equations for Potential Energy (Ep) and Kinetic Energy (Ek).
Ep = mgh and Ek = 1/2mv^2 ?
The following kinematic equation rearranged to show Acceleration (a):
s = ut + 1/2at^2.
What is:
a = 2/t^2 (s - ut)?
If there is a 5 kg block sitting on a table, this is the normal force produced and the object that is producing it.
What is 49.05 N produced by the table?
Comparing efficiency, a man takes in 100 J of energy and produces 45 J, while a machine takes in 500 J of energy and produces 310 J. Solve for each to find which is greater.
What is 0.45 efficiency for the man and 0.62 for the machine? The machine is more efficient.
