Motion and Forces

Front

What is the definition of velocity?

Back

Velocity is the rate at which an object changes its position, defined as displacement divided by the time taken.

Front

How does speed differ from 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 is the formula for calculating acceleration?

Back

Acceleration (a) can be calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What does a zero acceleration indicate about an object's motion?

Back

Zero acceleration indicates that the object's velocity is constant; it is not speeding up or slowing down.

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, along with the direction.

Front

What is the difference between distance and displacement?

Back

Distance is a scalar quantity that measures the total path length traveled, while displacement is a vector quantity that measures the shortest straight-line distance between two points.

Front

What is the significance of direction in velocity?

Back

Direction is crucial in velocity because it differentiates between two objects moving at the same speed but in different directions.

Front

How can you determine if an object is experiencing negative acceleration?

Back

An object is experiencing negative acceleration if its final velocity is less than its initial velocity.

Front

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

Back

The relationship is given by the formula: distance = speed × time.
