Motion

Front

What is negative acceleration?

Back

Negative acceleration, also known as deceleration, occurs when an object slows down, resulting in a decrease in its speed.

Front

How can you determine if an object is in motion?

Back

You can determine if an object is in motion by using reference points, which are stationary objects that help you observe the movement of the object in question.

Front

What is constant speed?

Back

Constant speed refers to when an object travels the same distance in equal intervals of time, meaning its speed does not change.

Front

What is average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken, and it may vary during the journey.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction, such as 24 km/hr South.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity, which can be an increase or decrease in speed.

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 does it mean for an object to be at rest?

Back

An object is at rest when it is not changing its position relative to a reference point.

Front

What is a reference point?

Back

A reference point is a stationary object or location used to determine the position or motion of another object.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.
