1D Kinematics and Free Fall

Front

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. It is defined as the shortest distance from the initial to the final position, along with the direction.

What is the formula for calculating final velocity in uniformly accelerated motion?

Front

What does a velocity-time graph represent?

Back

A velocity-time graph shows how the velocity of an object changes over time. The slope of the graph represents acceleration.

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), negative (slowing down), or zero (constant velocity).

Front

What is free fall?

Back

Free fall is the motion of an object under the influence of gravity alone, with no other forces acting on it.

Front

What happens to the velocity of an object at the highest point of its upward motion?

Back

At the highest point of its upward motion, the velocity of the object is zero, but the acceleration due to gravity is still acting on it, directed downward.

Front

What is the formula for acceleration?

Back

Front

What does a flat line on a velocity-time graph indicate?

Back

A flat line on a velocity-time graph indicates that the object is moving at a constant velocity, meaning there is no acceleration.

Front

What is the significance of a negative acceleration?

Back

Negative acceleration indicates that an object is slowing down. It can also occur when an object is moving in the opposite direction to its initial velocity.
