    Cards (51)

    • What is acceleration defined as?
      Rate of change of velocity
    • Acceleration is a vector quantity, meaning it has both magnitude and direction
    • Acceleration can only be positive.
      False
    • What does positive acceleration indicate?
      Increasing velocity
    • Acceleration is the rate of change of velocity
    • Velocity describes both the speed and direction of motion.
    • Match the property with the correct quantity:
      Definition ↔️ Rate of change of velocity
      Quantity ↔️ Vector (magnitude and direction)
      Sign ↔️ Can be positive or negative
    • What is the definition of acceleration?
      Rate of change of velocity
    • Acceleration is a scalar quantity.
      False
    • Acceleration can be positive, indicating increasing velocity
    • What is the formula for acceleration?
      a = \frac{v - u}{t}</latex>
    • Acceleration is a vector quantity, meaning it has both magnitude and direction
    • Negative acceleration indicates increasing velocity.
      False
    • What are the two properties of a vector quantity?
      Magnitude and direction
    • Steps to use the acceleration formula to solve a problem:
      1️⃣ Identify the given values for v, u, and t
      2️⃣ Substitute the values into the formula
      3️⃣ Calculate the acceleration
      4️⃣ Include the correct units (m/s²)
    • What is the unit of acceleration?
      m/s²
    • Uniform acceleration occurs when the velocity changes at a constant rate.
    • What happens to acceleration in non-uniform acceleration?
      It fluctuates
    • Match the type of acceleration with its characteristic:
      Uniform acceleration ↔️ Constant rate of change in velocity
      Non-uniform acceleration ↔️ Variable rate of change in velocity
    • What is the formula for calculating acceleration?
      a=a =vut \frac{v - u}{t}
    • A car accelerating from 10 m/s to 25 m/s in 5 seconds has an acceleration of 3 m/s².
    • The formula to calculate acceleration is a = (v - u) / t, where 'a' represents acceleration
    • The unit for acceleration is m/s².
    • The variable 'v' in the acceleration formula represents final velocity.
    • A car accelerating from 10 m/s to 25 m/s in 5 seconds has an acceleration of 3 m/s².
    • What is the acceleration of a train that slows down from 30 m/s to 12 m/s in 9 seconds?
      -2 m/s²
    • Acceleration is a vector quantity, meaning it has both magnitude and direction.
    • Negative acceleration indicates decreasing velocity.
    • What is the definition of acceleration?
      Rate of change of velocity
    • The formula for acceleration is a = (v - u) / t, where 't' represents time taken.
    • The symbol 'a' in the acceleration formula represents acceleration in m/s².
    • Match the symbol with its representation and unit:
      a ↔️ Acceleration, m/s²
      v ↔️ Final velocity, m/s
      u ↔️ Initial velocity, m/s
      t ↔️ Time taken, s
    • Order the following characteristics of uniform and non-uniform acceleration:
      1️⃣ Uniform acceleration: Velocity changes at a constant rate
      2️⃣ Uniform acceleration: Acceleration remains the same
      3️⃣ Non-uniform acceleration: Velocity changes at a variable rate
      4️⃣ Non-uniform acceleration: Acceleration fluctuates with time
    • In uniform acceleration, the rate of change in velocity is constant.
    • What is the unit for acceleration?
      m/s²
    • To calculate acceleration using the formula a = (v - u) / t, you must first identify the given values for v, u, and t.
    • The symbol 'a' in the acceleration formula represents acceleration in m/s².
    • What does the symbol 'u' represent in the formula for acceleration?
      Initial velocity
    • The unit for time taken in the acceleration formula is seconds
