Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What is the formula for calculating acceleration?

Back

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

Front

What does a graph with a steeper slope indicate in terms of acceleration?

Back

A steeper slope indicates greater acceleration.

Front

What is the metric unit for acceleration?

Back

The metric unit for acceleration is meters per second squared (m/s²).

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 a kinematic equation?

Back

A kinematic equation relates the variables of motion: displacement, initial velocity, final velocity, acceleration, and time.

Front

When can kinematic equations be applied?

Back

Kinematic equations can be applied when the acceleration is constant.

Front

What is the significance of the yard in measurement systems?

Back

The yard is a unit of length in the imperial system, not in the metric system.

Front

How do you calculate the distance traveled by an object under constant acceleration?

Back

Distance (d) = Initial Velocity (u) * Time (t) + 0.5 * Acceleration (a) * Time² (t²).

Front

What is the relationship between distance, speed, and time?

Back

Distance = Speed × Time.
