What is the acceleration of the box if the box moves at a constant speed to the right?

What is the acceleration of the box if the box moves at a constant speed to the right?

The box moves at a constant velocity and so its acceleration is zero. The spring force always acts in the direction needed to restore the spring to its original length. In this case, you stretched the spring, so the left end pulls toward the right or the +x direction.

What is an object moving at a constant speed?

An object moving at a constant speed is characterized by a uniform increase or decrease in the distance it covers per given time interval. It means that the object’s speed at the start of its motion (initial speed) is the same as its speed at the end of its motion (terminal speed).

Why is it harder to start to slide a heavy box across the floor than to keep it sliding?

Answer and Explanation: When you push a heavy box across the floor, the force you need to apply to start the box moving is greater than the force needed to keep the box moving. This is because the coefficient of static friction is greater than the coefficient of kinetic friction.

When a box is moving at a constant velocity?

As the box is moving with a constant velocity, the net force in the direction of motion must be zero. This is only possible if the magnitude of the applied force and the friction force are equal. Hence, we saw that the friction force is equal and opposite to the applied force.

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

Since the object is moving with a constant velocity, it means an acceleration of the body will be zero.

When an object moves with constant speed what is its acceleration?

If an objects speed remains constant, then its acceleration must be zero.

When an object moves with a constant speed and direction?

If an object moves with constant speed in a fixed direction, then the motion of the object is said to be uniform.

Is an object which is moving at a constant speed has momentum?

An object which is moving at a constant speed has momentum. An object can be traveling eastward and slowing down; its momentum is westward. Momentum is a conserved quantity; the momentum of an object is never changed. The momentum of an object varies directly with the speed of the object.

How do you move a large heavy box across the floor?

Use a piece of 1” x 2” lumber as a handle by rolling it up one end of the plastic. This will keep the plastic from tearing, and make it easier to pull. Then, pull the handle to drag the box easily across the floor.

Why is it difficult to push a box across the floor?

The primary force that makes it difficult to push the box across the floor would still be friction. This can be aggravated by the component of the force downwards used to push the box across the floor, as it contributes to the normal force.

Why must you constantly apply a force to a box across a floor?

Without this net external force, the box would continue to slide at a constant velocity (as stated in Newton’s first law of motion). What force acts on the box to slow it down? This force is called friction.

Can constant velocity be zero?

Derivative of velocity with respect to time is acceleration. That means if accelerations is zero, velocity must be constant. Now that constant could be anything like it could be 5 m/s . Also if the velocity is 0(which is itself a constant) also indicates that acceleration is zero.

What is the difference between speed and velocity?

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement. Put another way, speed is a scalar value, while velocity is a vector.

Why is work zero at constant velocity?

If a body is moving with a constant velocity, the net force on it is zero. So the net work done on it will be zero. Q. The work done on a block moving with constant velocity is zero.

How do you find the acceleration of a box?

According to Newton’s second law of motion, the acceleration of an object equals the net force acting on it divided by its mass, or a = F m . This equation for acceleration can be used to calculate the acceleration of an object when its mass and the net force acting on it are known.

Does acceleration happens if the object stays the same speed?

If you’re not changing your speed and you’re not changing your direction, then you simply cannot be accelerating—no matter how fast you’re going.

What type of acceleration does an object moving with constant speed in a circular path experience?

Centripetal acceleration ac is the acceleration experienced while in uniform circular motion. It always points toward the center of rotation.
