What else can I help you with?
Can there be a positive acceleration and a negative acceleration?
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.
Can both the velocity and acceleration be negative?
Yes, both velocity and acceleration can be negative. Negative velocity indicates movement in the opposite direction of a chosen positive direction, while negative acceleration indicates a decrease in velocity in the chosen positive direction.
Can an object have both negative velocity and acceleration?
Yes, an object can have negative velocity and negative acceleration if it is moving in the opposite direction of the positive axis. This would mean the object is both moving backwards and its speed is decreasing.
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 does positive and negative acceleration affect motion?
positive acceleration helps to increase the velocity for positive direction while negative acceleration resists the motion.
What is meant by positive acceleration and negative acceleration?
Positive acceleration = speeding up; speed increasing in the direction you're moving.Negative acceleration = slowing down; speed decreasing in the direction you're moving,or speed increasing in the opposite direction.
What has both a negative and positive?
An integer has both positive and negative numbers.
What are Statements about acceleration?
Acceleration is the rate of change of velocity with respect to time. Acceleration can be positive (speeding up), negative (slowing down), or zero (constant velocity). Acceleration is a vector quantity, meaning it has both magnitude and direction.
Does acceleration involve a direction?
Yes, acceleration is a vector quantity that involves both magnitude and direction. It indicates the rate of change of velocity with respect to time and can be positive or negative, depending on whether it is in the same direction as the velocity (positive) or opposite direction (negative).
What are three facts about acceleration?
Acceleration is the rate of change of velocity with respect to time. Acceleration can be positive (speeding up), negative (slowing down), or zero (constant velocity). Acceleration is a vector quantity, meaning it has both magnitude and direction.
Explain the difference between positive and negative acceleration?
well the difference between positive and negative velocity would have to be that if your motion speeds up than you have a positive and when or if your motion slows down then you would have a negative accelerarion!!!!
What is meaning of accelaration?
Acceleration is the rate at which an object's velocity changes over time. It can be a change in speed, direction, or both. A positive acceleration indicates speeding up, while negative acceleration (deceleration) indicates slowing down.
