If the rate of increase of velocity of a moving body in a particular direction constant all the time, then the acceleration is said to be uniform. Due to gravity, the acceleration of a freely falling body is 9.8 ms-2, that is, its velocity increases by 9.8 ms-2 for each successive second. Freefall is a special … Read more

When a force of large magnitudes acts on an object for a very short period, the force is called impulse force.

What is called vibratory motion? Vibratory motion, also known as oscillatory motion, is a type of movement where an object repeatedly moves back and forth around a fixed central position. Imagine a pendulum swinging or a guitar string vibrating – these are both examples of vibratory motion. Key characteristics of vibratory motion Examples of vibratory … Read more

The characteristic that a body wants to remain in its state forever is called inertia.Inertia is basically the tendency of objects to resist changes in their state of motion. Whether something is sitting still or zipping around, it wants to stay that way unless a force acts on it. Imagine you’re pushing a grocery cart … Read more

If the velocity of a body increases at the same rate in a certain direction then the acceleration of that body is called uniform acceleration. In physics, uniform acceleration refers to a specific type of motion where an object’s acceleration remains constant, meaning it increases its speed at a steady rate over equal intervals of … Read more

The decreasing rate of velocity of a body with time is called deceleration. In physics terms, deceleration is the rate at which something slows down. It’s like the opposite of acceleration, but instead of a positive “push,” it’s a negative “pull” that slows things down. We measure it in meters per second squared (m/s²), just … Read more

The body that is moving at a uniform speed does not have acceleration. Acceleration is the rate of change of velocity. So if the velocity of a body changes from time to time when it has acceleration. But when a body is moving at a uniform speed the magnitude of velocity does not change. So … Read more

The rate of change of position in time with its direction is called velocity. If we put an external force on a body as long as there is force there will be displacement. When there is no displacement the velocity of the body becomes zero.
