What else can I help you with?
What does it mean when velocity is negative?
When velocity is negative, it means that the object is moving in the opposite direction of its positive velocity.
What is positive acceleration formula?
The formula for positive acceleration is: acceleration = change in velocity / time taken. Positive acceleration means an increase in velocity over time.
What has to happen to a car's acceleration and velocity for a car's speed to increase and have a positive acceleration?
For a car's speed to increase and have a positive acceleration, the car's velocity needs to be increasing in the same direction as its acceleration. This means that the car is speeding up. When the velocity and acceleration have the same sign (both positive or both negative), the car's speed will increase.
The rate at which velocity changes?
The rate at which velocity changes is called acceleration. It describes how quickly an object's velocity is changing with respect to time. Positive acceleration means the object is speeding up, negative acceleration means it is slowing down, and zero acceleration means the velocity is constant.
Does acceleration have a negative or positive value if the velocity is increasing speed?
In this case, acceleration is positive. Negative acceleration would cause the object to slow down (decelerate.)
What does it mean when velocity is negative?
When velocity is negative, it means that the object is moving in the opposite direction of its positive velocity.
What is positive acceleration formula?
The formula for positive acceleration is: acceleration = change in velocity / time taken. Positive acceleration means an increase in velocity over time.
What has to happen to a car's acceleration and velocity for a car's speed to increase and have a positive acceleration?
For a car's speed to increase and have a positive acceleration, the car's velocity needs to be increasing in the same direction as its acceleration. This means that the car is speeding up. When the velocity and acceleration have the same sign (both positive or both negative), the car's speed will increase.
How are acceleration and speed alike?
They are not alike but they are related. A positive acceleration means an increase in velocity (speed). A negative acceleration means a decrease in velocity. Velocity (speed) has the dimensions of distance / time. Acceleration has the dimensions of distance/time2 or velocity/time.
The rate at which velocity changes?
The rate at which velocity changes is called acceleration. It describes how quickly an object's velocity is changing with respect to time. Positive acceleration means the object is speeding up, negative acceleration means it is slowing down, and zero acceleration means the velocity is constant.
How do you find the final velocity if the acceleration is negative?
It depends on what information you have. Also, velocity can be negative - it just means that the object is travelling in the direction opposite to the positive direction for the velocity vector.
Does acceleration have a negative or positive value if the velocity is increasing speed?
In this case, acceleration is positive. Negative acceleration would cause the object to slow down (decelerate.)
Why can velocity be positive or negitave?
Velocity can be a positive or a negative because velocity is a vector, which means it is also affected by direction. This that if one car is going +10 m/s and another is travelling at -10 m/s, this means that they are travelling the same speed in opposite directions.
If the acceleration is increasing with time will the velocity graph be a straight line concave up or concave down?
Concave up. "Acceleration is increasing with time" tells us that the derivative of acceleration is positive. Since acceleration is the derivative of velocity, this means that the second derivative of velocity is positive. By definition, having a non-negative second derivative means that velocity is concave up.
What is the rate of charge of velocity?
The rate of change of velocity is known as acceleration. It measures how quickly an object's velocity is changing over time. Positive acceleration means the object is speeding up, negative acceleration means it is slowing down, and zero acceleration means the velocity is constant.
In what directions are positive velocity's?
Positive velocity can be in any direction as long as the object is moving in that direction. For example, a car moving northward has a positive velocity in the north direction.
What does a positive acceleration mean?
Positive acceleration means that an object's velocity is increasing over time. This can happen when an object is speeding up in the direction of its motion.
