What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What is the formula for calculating distance when speed and time are known?

Back

Distance = Speed × Time.

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.

Front

What is the formula for calculating the circumference of a circle?

Back

Circumference = 2 × π × radius.

Front

What is the concept of constant speed?

Back

Constant speed means that an object covers equal distances in equal intervals of time, regardless of how small those intervals are.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, calculated as PE = mgh (mass × gravity × height).

Front

What is the significance of the peak height in projectile motion?

Back

At the peak height, the vertical velocity of the projectile is 0 m/s before it starts to descend.

Front

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

Back

Speed is directly proportional to distance and inversely proportional to time. If speed increases, distance increases if time remains constant.

Front

What is uniform circular motion?

Back

Uniform circular motion is the motion of an object traveling at a constant speed in a circular path, where the direction of the velocity vector is continuously changing.

Front

What is the formula for calculating average speed?

Back

Average Speed = Total Distance / Total Time.
