Front

What is the equation to determine the distance traveled by an object under constant acceleration?

Back

Δx = v₀t + 1/2at²

Front

What is the unit of weight in the International System of Units (SI)?

Back

Newtons

Front

What is the formula for the period of a pendulum?

Back

T = 2π√(L/g), where L is the length of the pendulum and g is the acceleration due to gravity.

Front

What does a horizontal line on a distance-time graph represent?

Back

Not moving.

Front

How do you calculate the time of flight for a projectile launched at an angle?

Back

Time of flight = (2 * v₀ * sin(θ)) / g, where v₀ is the initial velocity, θ is the launch angle, and g is the acceleration due to gravity.

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.81 m/s².

Front

What is the relationship between force, mass, and acceleration?

Back

F = ma, where F is force, m is mass, and a is acceleration.

Front

What is the definition of kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated as KE = 1/2 mv².

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the formula for calculating work done?

Back

Work = Force × Distance × cos(θ), where θ is the angle between the force and the direction of motion.
