When is a minus sign used in acceleration and deceleration formulas?
Wiki User
∙ 11y ago
A minus sign is used in acceleration and deceleration formulas to indicate direction. If the acceleration is in the opposite direction of the motion, a negative sign is used. For deceleration, which is a form of acceleration that opposes the motion, a negative sign is also used to show the decrease in velocity.

What is term declaration in physics?
In physics, term declaration refers to the process of clearly defining and identifying the different terms and variables used in an equation, theory, or concept. This is important to ensure that everyone understands the meaning and significance of each term being used in a particular context. Proper term declaration helps to avoid confusion and promote effective communication in scientific discussions.
What is the rate of decrease in velocity?
The rate of decrease in velocity is known as deceleration. It represents how quickly an object's velocity is decreasing over time. This can be calculated using the formula for acceleration, but with a negative sign to indicate a decrease in velocity.
The horse is galloping 13 ms. five seconds later after climbing the hill the horse is moving at 5.5 ms. find the acceleration that describes this change in velocity?
The acceleration can be calculated using the formula acceleration = (final velocity - initial velocity) / time. Substituting the values, we get acceleration = (5.5 m/s - 13 m/s) / 5 s = -1.5 m/s^2. The negative sign indicates deceleration.
A speed boat moving at a velocity of 25 m/s runs out of gas and drifts to a stop 3 minutes later 100 meters away. What is its rate of deceleration?
The initial velocity is 25 m/s, final velocity is 0 m/s, and the distance covered is 100 meters. Convert 3 minutes to seconds (3 minutes = 180 seconds). Use the equation v^2 = u^2 + 2as, where v is final velocity, u is initial velocity, a is acceleration, and s is distance. Solve for acceleration (deceleration in this case) to find it to be -0.3472 m/s^2. The negative sign indicates deceleration.
What is the acceleration of a projectile fired vertically down?
The acceleration of a projectile fired vertically down is equal to the acceleration due to gravity, which is -9.81 m/s^2. The negative sign indicates that the acceleration is in the downward direction.
How are deceleration and acceleration related?
Acceleration and deceleration are related by their their sign. Acceleration is positive ( increase in velocity with time) and deceleration is negative (decrease in velocity with time).
Do all excel formulas start with an sign?
All formulas begin with the equals sign. It is also possible to start with a plus sign, a minus sign or an @ sign, but an equals sign will be automatically put in front of it.All formulas begin with the equals sign.

How does Microsoft Excel perform calculations?
Many different functions can perform calculations or operations. Excel comes with hundreds of them. They can be accessed by clicking on the fx icon. The most commonly used function is usually the SUM function. It is generally used to add a range of values, but it can be used to do other kinds of calculations. It can be accessed by clicking on the Σ character on the toolbar.

Do two plus signs make a minus?
In addition and subtraction, if the plus sign is larger than the minus sign, then it's a plus. For example: +10 minus -20 = -10 If the plus sign is smaller than the minus sign, the answer will be a minus. For example: -10 minus + 20 = -10 In multiplication, if you have 2 plus signs, the answer will be a plus sign. If you have 2 minus signs, the answer will be a plus sign then, too. But if you have a plus and a minus sign, then the answer will be a minus. For example: +5 x + 2 = +10 -5 x - 2 = +10 -5 x +2 = -10
