What is the formula for calculating distance traveled under constant acceleration?

Back

Distance (d) = Initial Velocity (u) * Time (t) + 0.5 * Acceleration (a) * Time (t)^2

Front

Define angular acceleration.

Back

Angular acceleration is the rate of change of angular velocity over time, typically measured in radians per second squared (rad/s²).

Front

What is the moment of inertia for a rod about its end?

Back

The moment of inertia (I) for a rod about its end is given by the formula I = (1/3)ML², where M is the mass and L is the length of the rod.

Front

How do you calculate acceleration?

Back

Acceleration (a) = (Final Velocity (v) - Initial Velocity (u)) / Time (t).

Front

What happens to the acceleration of an object at the highest point of its projectile motion?

Back

At the highest point of its trajectory, the acceleration of a projectile is directed straight down due to gravity.

Front

Define potential energy.

Back

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

Front

What is kinetic energy and how is it calculated?

Back

Kinetic energy (KE) is the energy of an object in motion, calculated using the formula KE = 0.5 * m * v², where m is mass and v is velocity.

Front

Explain the concept of uniform motion.

Back

Uniform motion refers to motion at a constant speed in a straight line, meaning the object covers equal distances in equal intervals of time.

Front

What is the significance of air resistance in projectile motion?

Back

Air resistance opposes the motion of a projectile, affecting its trajectory and reducing its range compared to ideal conditions without air resistance.

Front

Define the term 'net force'.

Back

Net force is the vector sum of all the forces acting on an object, determining the object's acceleration according to Newton's second law (F = ma).
