An object can change velocity in a number of ways: it can slow down, it can speed up, or it can change direction. A change in speed, or a change in direction, or a change in both speed and direction means that the object has a change in velocity.

Whenever, one of the Component including speed or direction changes, Velocity of the body change. It is a possible cause to this to be done. ♤ If speed ups or slows down. If Speed downs, acceleration too decreases.

Answer: The body is in motion with constant acceleration. Thus, the speed of the body moving in a straight line increases or decreases by the same amount at equal intervals of time. The velocity of an object can change if: Its speed changes.

No, a body can not have its velocity constant, while its speed varies. Rather, it can have its speed constant and its velocity varying. For example in a uniform circular motion.

Answer. Answer: “Yes” a body can have zero velocity and can still accelerate simultaneously. When an object is thrown upwards, then at the maximum height, velocity of body is zero at that instant but it has acceleration due to gravity.

Aristotle’s Laws of Motion. Nothing moves unless you push it. [ it is moved by a mover] Some motion is natural for the sublunar elements, rectilinear motion to or away from the earth’s center for the supralunar quintessence, circular motion. All other motion is violent, and requires a mover.

“Every body continues to be in its state of rest or of uniform motion in a straight line unless compelled by an unbalanced external force.” The intrinsic property of material body which resists a change in its state of rest or of uniform motion along a straight line is called inertia .

If a moving body comes to rest, then its acceleration is negative, as it’s velocity becomes zero. therefore the acceleration is also zero.

When a body moves with constant velocity, then acceleration will be zero. So, the slope of the velocity-time graph will be zero. Therefore, we can say that the correct answer to the question asking about the slope of the velocity-time graph for motion with uniform velocity is equal to zero.

For the body to be stationary, net external force acting on it must be equal to zero which is possible only when the combination of forces acting on it balance each other.

School bag has the mass greater than the pin, pen and book. So, it offers greater resistance and hence had higher inertia.

Answer: the car has more inertia as more the mass the more inertia… HOPE IT HELPS! !

Newton’s first law states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. This postulate is known as the law of inertia.

The focus of Lesson 1 is Newton’s first law of motion – sometimes referred to as the law of inertia. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
