Acceleration means: Any change of speed or direction.
Three simple examples are:
1). the car slowing down, because of either mashing the brake or going up a hill;
2). the car speeding up, because of either mashing the gas pedal or going down a hill;
3). the car going around a curve in the road, even of its speed doesn't change.
Yes, increasing acceleration means that the rate of change of velocity is increasing, which implies positive acceleration. Positive acceleration corresponds to speeding up, while negative acceleration (deceleration) corresponds to slowing down.
Some examples of acceleration questions that can be used to assess students' understanding of the concept include: What is the formula for calculating acceleration? How does acceleration differ from velocity? Can an object have acceleration if its speed is constant? Explain. Describe a scenario where an object experiences positive acceleration. How does mass affect an object's acceleration when the same force is applied?
The formula for positive acceleration is: acceleration = change in velocity / time taken. Positive acceleration means an increase in velocity over time.
In this case, acceleration is positive. Negative acceleration would cause the object to slow down (decelerate.)
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 formula for positive acceleration is: acceleration = change in velocity / time taken. Positive acceleration means an increase in velocity over time.
Yes, acceleration can be positive and negative because acceleration is a vector. It has both direction and magnitude. The direction is what makes it positive or negative. Negative acceleration is usually called deceleration.
In this case, acceleration is positive. Negative acceleration would cause the object to slow down (decelerate.)
Examples of acceleration are change in speed, change in direction, or both.
Positive is speeding up and negative is slowing down
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.
Positive acceleration could be called "speeding up" if you felt like it.
A negative acceleration refers to a decrease in velocity, while a positive acceleration refers to an increase in velocity. Negative acceleration occurs when the speed of an object is decreasing, such as when it is slowing down. Positive acceleration occurs when the speed of an object is increasing, such as when it is speeding up.
Positive acceleration is an increase in velocity in the direction in which motion is being measured.
Positive acceleration occurs when an object's velocity is increasing over time, while negative acceleration (or deceleration) happens when an object's velocity is decreasing over time. Positive acceleration can be due to speeding up, turning, or changing direction, while negative acceleration is typically caused by slowing down or stopping.
