What is velocity?

Back

Velocity is the rate of change of displacement of an object, defined as the distance traveled in a specific direction per unit of time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down or decelerating.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv.

Front

How does doubling the mass of an object affect its momentum if velocity remains constant?

Back

Doubling the mass of an object will double its momentum if the velocity remains constant.

Front

What happens to the momentum of an object if its velocity is halved?

Back

If the velocity of an object is halved, its momentum is also halved, assuming mass remains constant.

Front

What is the formula for calculating distance?

Back

Distance can be calculated using the formula: Distance = Speed × Time.

Front

What is free fall?

Back

Free fall is the motion of an object under the influence of gravitational force only, with no other forces acting on it.

Front

What is the significance of a velocity vs. time graph?

Back

A velocity vs. time graph shows how the velocity of an object changes over time, allowing for the determination of acceleration.
