What is 1D Kinematics?

Back

1D Kinematics is the branch of mechanics that deals with the motion of objects along a straight line, focusing on concepts such as displacement, velocity, acceleration, and time.

Front

Define displacement.

Back

Displacement is the vector quantity that represents the change in position of an object, measured as the shortest distance from the initial to the final position, along with the direction.

Front

What is the formula for calculating average velocity?

Back

Average velocity is calculated using the formula: Average Velocity = (Final Position - Initial Position) / Time.

Front

What is acceleration?

Back

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

Front

How do you calculate impulse?

Back

Impulse is calculated using the formula: Impulse = Force x Time.

Front

What is the relationship between force and acceleration?

Back

According to Newton's second law, the relationship is given by the formula: Force = Mass x Acceleration.

Front

What does a positive acceleration indicate?

Back

A positive acceleration indicates that an object is speeding up in the direction of its motion.

Front

What does a negative acceleration indicate?

Back

A negative acceleration (deceleration) indicates that an object is slowing down.

Front

How do you determine the direction of acceleration?

Back

The direction of acceleration is determined by the change in velocity; it is in the same direction as the velocity if speeding up and opposite if slowing down.

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 over the time interval.
