What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object changes its speed or direction.

Why does a car accelerate when going around a corner at constant speed?

Back

The car accelerates because it is changing direction, which is a change in velocity.

Front

What happens to objects of different masses when dropped from rest in a vacuum?

Back

They will fall with equal accelerations and with equal displacements.

Front

How do you calculate the time it takes for a train to pass a point?

Back

Use the formula: time = distance / average speed.

Front

What is the formula for acceleration?

Back

Acceleration (a) = (final velocity (v_f) - initial velocity (v_i)) / time (t).

Front

If a roller coaster accelerates from 6.0 m/s to 70 m/s in 4 seconds, what is the acceleration?

Back

The acceleration is 16 m/s².

Front

How do you calculate distance covered during acceleration?

Back

Use the formula: distance = initial velocity * time + 0.5 * acceleration * time².

Front

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

Back

Speed = Distance / Time.

Front

What is the unit of acceleration?

Back

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

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 speed and direction.
