Front

What is the formula to calculate the distance traveled by an object under constant acceleration?

Back

Distance (d) = v_i * t + 0.5 * a * t^2, where v_i is the initial velocity, a is acceleration, and t is time.

Front

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

Back

Newton's Second Law: F = m * a, where F is force, m is mass, and a is acceleration.

Front

How do you calculate acceleration from force and mass?

Back

Acceleration (a) = Force (F) / Mass (m).

Front

What is the coefficient of friction (μ) and how is it calculated?

Back

Coefficient of friction (μ) = F_f / F_N, where F_f is the force of friction and F_N is the normal force.

Front

What does a velocity-time graph represent?

Back

A velocity-time graph shows how the velocity of an object changes over time; the slope represents acceleration.

Front

What is the significance of a negative acceleration?

Back

Negative acceleration indicates that an object is slowing down (decelerating).

Front

How do you convert meters to centimeters?

Back

To convert meters to centimeters, multiply the number of meters by 100.

Front

What does it mean for an object to be in uniform motion?

Back

An object is in uniform motion if it travels equal distances in equal intervals of time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is the formula for calculating kinetic energy?

Back

Kinetic Energy (KE) = 0.5 * m * v^2, where m is mass and v is velocity.
