Kinematics

Front

What is Kinematics?

Back

Kinematics is the branch of mechanics that describes the motion of objects without considering the forces that cause the motion.

Front

Define velocity.

Back

Velocity is the speed of an object in a specific direction, expressed in units such as meters per second (m/s) or miles per hour (mph).

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) is calculated using the formula: a = (final velocity - initial velocity) / time.

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

How do you calculate the distance traveled under constant acceleration?

Back

Distance (d) can be calculated using the formula: d = initial velocity * time + 0.5 * acceleration * time^2.

Front

What is hang time in projectile motion?

Back

Hang time is the total time an object spends in the air during its flight.

Front

What happens to the acceleration of an object in free fall?

Back

In free fall, the acceleration of an object remains constant at approximately 9.81 m/s² due to gravity, regardless of its mass.

Front

How do you determine the final velocity of an object that is decelerating?

Back

Final velocity can be determined using the formula: final velocity = initial velocity - (acceleration * time).

Front

What is the significance of a negative acceleration?

Back

Negative acceleration indicates that an object is slowing down or decelerating.

Front

What is the formula for calculating the time of flight for an object thrown vertically?

Back

Time of flight (t) can be calculated using the formula: t = 2 * (initial velocity / acceleration due to gravity).
