Kinematics 1

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 displacement?

Back

Displacement is the vector quantity that represents the change in position of an object. It is the shortest distance from the initial to the final position.

Front

What is the formula for calculating displacement with constant acceleration?

Back

The formula is: \( s = ut + \frac{1}{2}at^2 \) where \( s \) is displacement, \( u \) is 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 acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time. It can be positive (speeding up) or negative (slowing down).

Front

What is the formula for final velocity with constant acceleration?

Back

The formula is: \( v = u + at \) where \( v \) is final velocity, \( u \) is initial velocity, \( a \) is acceleration, and \( t \) is time.

Front

How do you calculate the distance traveled when an object comes to a stop?

Back

Use the formula: \( s = \frac{v^2 - u^2}{2a} \) where \( s \) is distance, \( v \) is final velocity (0 for stopping), \( u \) is initial velocity, and \( a \) is acceleration.

Front

What is uniform acceleration?

Back

Uniform acceleration occurs when an object's velocity changes at a constant rate over time.

Front

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

Back

The area under a velocity-time graph represents the displacement of the object during that time interval.

Front

What is the initial velocity in the context of motion?

Back

Initial velocity is the velocity of an object at the start of a time interval.
