Can an object moving constant speed have an acceleration?

Can an object accelerate if it’s moving with constant speed? Yup! Many people find this counter-intuitive at first because they forget that changes in the direction of motion of an object—even if the object is maintaining a constant speed—still count as acceleration.

What is the acceleration of an object that is moving at a constant speed?

zero acceleration
If an object is moving with a constant velocity, then by definition it has zero acceleration. So there is no net force acting on the object.

Can an object have constant speed and still be accelerating give an example?

For example, a car going on a roundabout can have a constant speed but since it will have a constantly changing direction, it can have a varying velocity as velocity is a vector quantity and depends on the direction of the car. Hence, a body can have a constant speed and still be accelerating.

Is it possible that an object with a constant acceleration but with zero velocity?

(a) An object with a constant acceleration but with zero velocity. One example of this is the vertical motion of an object. When the object is thrown upwards and reaches the maximum height, the velocity of the body becomes zero, but it still accelerates with constant acceleration.

Is it possible to accelerate an object without doing any work on the object?

Yes, it is possible that work done is zero even when a body is in accelerated motion. This happens when force is acting in a direction perpendicular to the direction of motion. Hence work done is zero, thoudh the motion is accelerated.

Can a body moving at a constant speed have acceleration Class 9?

Yes, it is possible. When a body is in a uniform circular motion, its speed remains constant. But its acceleration is non-zero as the direction of motion is changing continuously. A body moving with a uniform speed can have acceleration.

Can a body have constant speed and still be accelerating justify your answer either by giving scientific reason or by giving example?

Yes, A body can have constant speed but still accelerate as in case of uniform circular motion. In uniform circular motion speed remains constant and direction of velocity changes with every point in the direction of tangent drawn from that point.

Is it possible for an object moving in a certain direction with an acceleration in the perpendicular direction if possible give an example?

Explanation: An object is a moving in a certain direction with an acceleration in the perpendicular direction. The above condition is possible. Example of such a situation in real life would be when a stone tied to a string is whirled in a circular path.

Is it possible for a body to have zero acceleration and still be moving how?

Yes, an object can have zero velocity and still be accelerating simultaneously. Let us consider an object moving in the forward direction. Then the object will start to move in the backward direction.

What did Galileo have to do with Newton?

Galileo determined the laws of gravity and explored the laws of motion on earth. Armed with these solidified theories of dynamics, Newton proved that the force that acted on planets and moons was the same force that caused a stone to fall to the ground: gravity.

What does the law of acceleration?

Newton’s second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

Why do things in free fall accelerate?

Free-fall is the motion of objects that move under the sole influence of gravity; free-falling objects do not encounter air resistance. More massive objects will only fall faster if there is an appreciable amount of air resistance present. The actual explanation of why all objects accelerate at the same rate involves the concepts of force and mass.

Can velocity change when acceleration is constant?

A object undergoing a constant acceleration has a constantly changing velocity. If the acceleration always points in the same direction as the velocity, the trajectory will be no different than if there were no acceleration, but in general acceleration will change the trajectory.

What is the formula for calculating acceleration?

The formula for acceleration is given as a = (v2 – v1) / (t2 – t1), where “a” denotes the acceleration, “v2” indicates the final velocity, “v1” represents the initial velocity and “t2 – t1” is the time interval between the final and initial velocities.

When does an object accelerate?

An object accelerates when a force is acting on the object. This given by the Newton’s second law F=ma, where F is the net force act on the object, m is the mass of the object and a is the acceleration of the object. The reason why objects accelerate as they fall is because the gravity of earth acts on the object.
