Kinematics 2

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

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time, measured in meters per second squared (m/s²).

Front

How do you calculate final velocity with constant acceleration?

Back

Final velocity (v) can be calculated using the formula: v = u + at, where u is the initial velocity, a is acceleration, and t is time.

Front

What is the formula for distance traveled under constant acceleration?

Back

Distance (s) can be calculated using the formula: s = ut + 0.5at², where u is the initial velocity, a is acceleration, and t is 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

What is the unit of acceleration?

Back

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

Front

How do you find the distance traveled when starting from rest?

Back

When starting from rest (u = 0), the distance can be calculated using the formula: s = 0.5at².

Front

What is the significance of the area under a velocity-time graph?

Back

The area under a velocity-time graph represents the distance traveled by the object.

Front

How do you calculate the distance traveled when decelerating?

Back

When decelerating, use the formula: s = ut + 0.5at², where 'a' will be negative.

Front

What is uniform acceleration?

Back

Uniform acceleration occurs when an object's acceleration is constant over time.
