Velocity & Motion

Front

What is the formula to calculate speed?

Back

Speed = Distance ÷ 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

Define acceleration.

Back

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

Front

What is the unit of speed in the International System of Units (SI)?

Back

The unit of speed in SI is meters per second (m/s).

Front

If an object is moving at a constant speed, what can be said about its acceleration?

Back

If an object is moving at a constant speed, its acceleration is zero.

Front

What is the formula for calculating distance when speed and time are known?

Back

Distance = Speed × Time

Front

What does it mean for an object to be in motion?

Back

An object is in motion if its position changes relative to a reference point over time.

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

Front

What is the significance of direction in velocity?

Back

Direction is significant in velocity because it determines the object's path and is essential for understanding motion in a specific direction.

Front

What is the relationship between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the shortest straight-line distance from the initial to the final position, including direction.
