What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv, where p is momentum, m is mass, and v is velocity.

Front

How do you calculate the momentum of an object?

Back

Momentum (p) is calculated using the formula p = mv, where m is the mass of the object and v is its velocity.

Front

What is the principle of conservation of momentum?

Back

The principle states that in a closed system, the total momentum before an event (like a collision) is equal to the total momentum after the event.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration, commonly represented as PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What happens to potential energy when an object is lifted?

Back

When an object is lifted, its height increases, resulting in an increase in potential energy.

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 acceleration?

Back

Acceleration is the rate of change of velocity of an object, calculated as a = (v_f - v_i) / t, where v_f is final velocity, v_i is initial velocity, and t is time.

Front

What is uniform circular motion?

Back

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

Front

How do you calculate the acceleration of an object in circular motion?

Back

The acceleration (centripetal acceleration) of an object in circular motion is calculated using the formula a = v^2 / r, where v is the speed and r is the radius of the circular path.

What is free fall?

Back

Free fall is the motion of an object under the influence of gravity only, with no air resistance acting on it.
