Speed, Velocity, Acceleration

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in units like km/hr or m/s.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can occur when an object speeds up, slows down, or changes direction.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What unit is commonly used to measure speed?

Back

Common units for speed include kilometers per hour (km/hr) and meters per second (m/s).

Front

How does acceleration differ from speed?

Back

Acceleration refers to the change in velocity over time, while speed is a measure of how fast an object is moving regardless of direction.

Front

What happens to an object's velocity when it accelerates?

Back

An object's velocity increases if it speeds up, decreases if it slows down, or changes direction if it turns.

Front

What is the relationship between distance, speed, and time?

Back

Distance is equal to speed multiplied by time (Distance = Speed x Time).

Front

What is uniform motion?

Back

Uniform motion occurs when an object moves at a constant speed in a straight line.

Front

What is the difference between average speed and instantaneous speed?

Back

Average speed is the total distance traveled divided by the total time taken, while instantaneous speed is the speed of an object at a specific moment in time.
