Quick question about acceleration.

In summary, acceleration is the rate of change of an object's velocity with respect to time. It is typically measured in units of meters per second squared (m/s²) or feet per second squared (ft/s²) and can also be measured in units of g (gravity). Acceleration is caused by a net force acting on an object and is related to velocity as the change in velocity over time. It can be negative, also known as deceleration or retardation, and its direction is opposite to the direction of motion.

Homework Statement



If I had an acceleration of A=69g's can I just say A=69(9.81) = 676.89m/s^2?

Depends on the context. You are essentially stating the same thing just in different words/numbers. In physics, we would prefer the form (m/s^2) however,.

Yes, you are correct. Acceleration is typically measured in meters per second squared (m/s^2), so multiplying 69g's by the acceleration due to gravity (9.81m/s^2) will give you the correct value in m/s^2. It is important to note that 1g is equal to 9.81m/s^2, so an acceleration of 69g's is extremely high and would likely only occur in extreme circumstances (such as during a rocket launch).
 

1. What is acceleration?

Acceleration is the rate of change of an object's velocity with respect to time. It is a vector quantity, meaning it has both magnitude and direction.

2. How is acceleration measured?

Acceleration is typically measured in units of meters per second squared (m/s²) in the metric system or feet per second squared (ft/s²) in the imperial system. It can also be measured in units of g (gravity), where 1 g is equal to 9.8 m/s².

3. What causes acceleration?

Acceleration is caused by a net force acting on an object. This force can be applied by another object, such as a person pushing a car, or by a force of nature, such as gravity pulling an object towards the Earth.

4. How is acceleration related to velocity?

Acceleration is the change in an object's velocity over time. This means that an object with a constant acceleration will experience a change in its velocity over time. If the acceleration is positive, the velocity will increase. If the acceleration is negative, the velocity will decrease.

5. Can acceleration be negative?

Yes, acceleration can be negative. This occurs when the object is slowing down or decelerating. Negative acceleration is also known as deceleration or retardation. It is important to note that the direction of the negative acceleration is opposite to the direction of motion.
