What is the formula to find the vertical component of velocity when given the angle and horizontal component?

Back

Vertical component (Vy) = Horizontal component (Vx) * tan(angle)

Front

Define frequency in the context of pendulums.

Back

Frequency is the number of complete cycles of motion per unit time, typically measured in Hertz (Hz).

What is the relationship between the length of a pendulum and its frequency?

Back

The frequency of a pendulum is inversely proportional to the square root of its length. Longer pendulums have lower frequencies.

Front

What is the range of possible values for the sum of two forces?

Back

The sum of two forces can range from the absolute difference to the absolute sum of their magnitudes.

Front

What is Newton's second law of motion?

Back

Newton's second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).

Front

How do you calculate the mass of an object if you know the force applied and the time taken to stop it?

Back

Mass (m) = Force (F) / Acceleration (a), where acceleration can be calculated from the change in velocity over time.

What is the formula for calculating the speed of an object in free fall after a certain time?

Back

Speed (v) = g * t, where g is the acceleration due to gravity (approximately 9.81 m/s²) and t is the time in seconds.

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately 9.81 m/s².

Define the term 'net force'.

Back

Net force is the vector sum of all the forces acting on an object, determining its acceleration.

What is the significance of the angle in projectile motion?

Back

The angle of projection affects the range, height, and time of flight of a projectile.
