Why is the distance time graph a straight line for?
A straight line on a distance - time graph represents a "constant velocity".
What type of acceleration does a trapezium on a velocity time graph represents?
A period of constant positive acceleration;a second period of zero acceleration; a third period of constant negative acceleration.
What is horizontal line in a speed graph?
Assuming it is a spped v/s time graph, a horizontal line represents motion at a constant speed.
What quantity does the slope of a distance vs time squared graph represent?
Since distance is 1/2 at^2 where a is acceleration, it represents one half of the acceleration
Is direct variation a function?
A direct variation is a situation in which two quantities -- such as hours and pay, or distance and time -- increase or decrease at the same rate. The ratio between the quantities is constant; that is, as one quantity doubles, the other quantity also doubles. so yes it is. -add on- A direct variation is in the form y=ax where a is an constant.
An exponential growth function represents a quantity that has a constant halving time?
That would be an exponential decay curve or negative growth curve.
An exponential decay function represents a quantity that has a decreasing halving time?
exponential decay doesnt have to have a decreasing halving time. it just decays at a certain percentage every time, which might be 50% or might not
Does an exponential growth function represents a quantity that has a constant doubling time?
False
An exponential growth function represents a quantity that has a constant doubling time?
True
Is an exponential decay function represent a quantity that has a constant halving time?
A quantity is said to be subject to exponential decay if it decreases at a rate proportional to its value. The time required for the decaying quantity to fall to one half of its initial value.Radioactive decay is a good example where the half life is constant over the entire decay time.In non-exponential decay, half life is not constant.
An exponential decay function represents a quantity that has a constant doubling time?
depends it can be true or false Apex: False
What is The rate of a changing quantity is the amount it changes per single increment of time?
The rate of a changing quantity is the derivative of that quantity with respect to time. It represents how fast the quantity is changing at a specific point in time. This rate can be constant or variable depending on the nature of the change.
What is the time rate of change of displacement?
The time rate of change of displacement is velocity, which represents how the position of an object changes over time. It is a vector quantity that includes both the speed and direction in which an object is moving.
What is the dimensional formula of force constant?
The dimensional formula of force constant is MLT⁻², where M represents mass, L represents length, and T represents time.
What do you mean by the dimensional formula and dimension of physical quantity?
The dimensional formula of a physical quantity represents how it is composed of fundamental dimensions like length, mass, and time. For example, the dimensional formula of velocity is [LT^-1] where L represents length and T represents time. The dimension of a physical quantity refers to the type of fundamental dimension it represents, like length, mass, or time.
A quantity that represents the rate of change of distance over a period of time?
Speed
Can an object have a constant spped and velocity at the same time?
No, an object cannot have a constant speed and velocity at the same time. Speed is a scalar quantity that describes how fast an object is moving, while velocity is a vector quantity that includes both speed and direction. If the velocity is constant, then the speed can be constant as well, but the object must maintain a consistent direction.
