Speed, Velocity, Acceleration

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 the speed and direction of the object's motion.

Front

Define acceleration in terms of motion.

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 net force of 0 N indicate about an object's motion?

Back

A net force of 0 N indicates that the object is either at rest or moving at a constant velocity.

Front

What is an example of constant speed?

Back

An example of constant speed is a car traveling at 60 miles per hour on a straight road without changing speed.

Front

What is the unit of measurement for acceleration?

Back

The unit of measurement for acceleration is meters per second squared (m/s²).

Front

How does friction affect acceleration?

Back

Friction opposes motion and can decrease the acceleration of an object.

Front

What is the significance of direction in velocity?

Back

Direction is significant in velocity because it determines the object's path and can change even if the speed remains constant.

Front

What is an example of negative acceleration?

Back

An example of negative acceleration is a car slowing down as it approaches a stop sign.

Front

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

Back

An object in constant motion maintains the same speed and direction over time.
