Acceleration Practice

Front

What is acceleration?

Back

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

Front

What are the units of acceleration?

Back

The units of acceleration are meters per second squared (m/s²).

Front

How do you calculate acceleration from velocity and time?

Back

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

Front

If an object starts from rest and reaches a velocity of 30 m/s in 5 seconds, what is its acceleration?

Back

The acceleration is 6 m/s².

Front

A car accelerates from 0 to 60 m/s in 10 seconds. What is its acceleration?

Back

The acceleration is 6 m/s².

Front

What is the formula for calculating final velocity when initial velocity, acceleration, and time are known?

Back

Final velocity (v) can be calculated using the formula: v = initial velocity + (acceleration × time).

Front

If a box slides down an inclined plane and attains a velocity of 27 m/s in 3 seconds, what is the acceleration?

Back

The acceleration is 9 m/s².

Front

What is the relationship between acceleration, force, and mass according to Newton's second law?

Back

According to Newton's second law, force (F) is equal to mass (m) times acceleration (a), or F = m × a.

Front

How long does it take for a rocket with an acceleration of 90 m/s² to reach a speed of 2430 m/s?

Back

It takes 27 seconds.

Front

What is the acceleration of an object that speeds up from 0 to 9 m/s in 24 seconds?

Back

The acceleration is 0.375 m/s².
