Is motion possible without force?

Is motion possible without force?

Yes, it is possible for motion to exist without force. An application of an external force is required to change the state of the motion. When the force is removed, the object acquires a new constant speed/direction.

Does force cause motion?

Force and Motion Forces cause all motions. Everytime the motion of an object changes, it’s because a force has been applied to it. Force can cause a stationary object to start moving or a moving object to change its speed or direction or both. A change in the speed or direction of an object is called acceleration.

Can an object be in equilibrium if only one force acts on it?

If there is only one external force (or torque) acting on an object, it cannot be in equilibrium. True, as the sum of forces cannot be zero in this case unless the force itself is zero. If an object is in equilibrium there must be an even number of forces acting on it.

Can an object accelerate without force?

“An object does not accelerate unless a net force acts on it.” “If there’s a net force acting on an object, then it will continue to accelerate unless that net force is zero.”

Can an object have a speed of zero while it has an acceleration that is not zero?

Yes. Consider a object which reverses direction due to acceleration in opposite direction. Then when the object reverses direction, momentarily instantaneous speed is zero but acceleration is not.

Can an object have acceleration without speeding up or slowing down?

Yes it can. Acceleration is defined as he rate of change of velocity. The changing direction can even change the velocity. It means that if an object continues to go at the same speed without slowing down or going fast but changes its direction then definitely the velocity changes.

Can a body have acceleration with zero velocity?

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

Is constant speed 0 velocity?

No, it doesn’t. Velocity is a vectorial quantity, it has magnitude (speed) and direction. Even though the speed is constant in this particular example, the direction changes all the time. The velocity of an object changes when the net force acting on it is not zero.

Can you move with constant velocity and not constant speed?

Motion with Constant Velocity: When an object is moving with constant velocity, it does not change direction nor speed and therefore is represented as a straight line when graphed as distance over time. You can also obtain an object’s velocity if you know its trace over time.

Does constant velocity mean no force?

If a body is moving with constant velocity, acceleration is zero. So net force acting on it will be also zero. But the body has energy due to its constant motion. So even if the body is moving with constant velocity, it can impart its momentum to other body.

Can velocity change if speed is constant?

While the speed of the object is constant, its velocity is changing. Velocity, being a vector, has a constant magnitude but a changing direction.

What does it mean if an object has a negative acceleration?

That means that the direction of the acceleration determines whether you will be adding to or subtracting from the velocity. Mathematically, a negative acceleration means you will subtract from the current value of the velocity, and a positive acceleration means you will add to the current value of the velocity.

What force is required to keep it sliding at constant velocity?

Newton’s law states quite the opposite; no force is needed to maintain a constant velocity. Forces produce a change in velocity not the velocity itself. If all external forces are balanced and the velocity is zero, then the object remains at rest.

What will never speed up an object?

According to Newton’s first law of motion, an object moving at a constant speed in a straight path will continue to do so until a net force acts upon it. Friction brings most moving objects to a stop. Friction will never speed up an object. Friction can be reduced but never eliminated.

When an object is not moving at all the velocity must be zero?

An object at rest is one with zero velocity.

Can an object be moving if its acceleration is zero?

4) a) Can an object be moving when its acceleration is zero? Yes, an object that was set in motion in the past by some force, but that is no longer being acted on by a net force, is moving but with zero acceleration, i.e. it is moving at constant velocity.

Can a moving object have a net force of zero?

Newton’s First Law of Motion An object’s velocity (a vector) does not change if and only if the net force acting on the object is zero. In other words, if there is no net force on an object, its speed and direction of motion do not change (including if it is at rest).

What would be the net force on an object if the object’s acceleration is 0?

Acceleration is the change of velocity per unit time, so if there is no force, all we know is that the acceleration is zero. Net force is the vector sum of all forces acting on the object.

What force is needed to accelerate a 10kg mass?

This is given by the familiar equation: →F=m→a . Given a mass of 10kg and an acceleration of 3ms2 , we can calculate the net force on the bowling ball from the above equation. Therefore, 30N of force is required to accelerate the bowling ball down the alleyway at a rate of 3ms2 .

Is it possible for an object to move if no force is acting on it explain?

Is it possible for an object to be in motion if no net force is acting on it? yes it is possible because when the net force is zero and acceleration is zero. so if the object has some constant velocity it continues with the same velocity until it has some external acceleration.
