Physical Science Equations & Conversion Practice

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It is measured in meters per second squared (m/s²).

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken. Formula: Average Speed = Total Distance / Total Time.

Front

What is the formula for force?

Back

Force is calculated using Newton's second law: Force (F) = Mass (m) × Acceleration (a). It is measured in Newtons (N).

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is the difference between instantaneous speed and average speed?

Back

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

Front

How do you find the change in velocity?

Back

Change in velocity is found by subtracting the initial velocity from the final velocity: Change in Velocity = Final Velocity - Initial Velocity.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) is calculated using the formula: a = (Final Velocity - Initial Velocity) / Time.

Front

What is the relationship between mass and acceleration?

Back

According to Newton's second law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is average velocity?

Back

Average velocity is the total displacement divided by the total time taken. It is a vector quantity.

Front

What is the formula for calculating average velocity?

Back

Average Velocity = Total Displacement / Total Time.
