Is acceleration possible without force?

Explanation: If there are no forces acting upon the object, then there is no acceleration. If there is no acceleration, then the object will move with a constant velocity. Since we know that the mass cannot be zero, the acceleration must be zero.

What is an example of a force that causes acceleration?

The cause of acceleration is force. When a hockey puck is at rest, the net force on it (gravity and the support force) is balanced, so the puck is in equilibrium. Hit the puck (that is, apply an unbalanced force to it) and the puck experiences a change in motion—it accelerates.

Can a body with zero velocity be accelerating?

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

Can acceleration exist without velocity?

A body can have acceleration even if its velocity is zero at a given instant.

What force is directly responsible for making the car accelerate?

friction
So, there are lots of other forces going on internal to the car. But the force directly responsible for making the car accelerate is the road’s friction.

What are the factors that can affect the acceleration of an object?

The acceleration of an object depends on the mass of the object and the amount of the force applied to it. It states that the acceleration of an object increases with increased force and decreases with increased mass.

Can a body have acceleration even at rest if yes give an example?

Hello yaar, Yes, a body can have acceleration while at rest. For Example:- i)The best example for this is acceleration due to gravity(g). It acts on a body even if the body has no velocity.

Can a body have zero speed but non-zero velocity?

Answer: (a) True. When a body begins to fall freely under gravity, its speed is zero but it has non-zero acceleration of . Speed is the magnitude of velocity and the magnitude of non-zero velocity cannot be zero.

What force causes an automobile to move?

friction force
The force that causes an automobile to move is the friction force. The tires rotate and try to push the ground backwards.

Which force actually moves the car?

The most succinct answer to your question is that the friction force is what actually moves the car. There are other factors and forces which must act to make the car move, but ultimately, the single force responsible for the movement is this friction force.

How does force affect acceleration of an object?

The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.

Does force really cause acceleration?

Force really does not cause acceleration. Only constant application of force causes acceleration. Actual Newton’s second Law is F = mv which can also be written as F/t = ma. Following is the original statement and explanation of second law (English Translation)

What is the relationship between acceleration and velocity?

Acceleration and velocity. Newton’s second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate. In the simplest case, a force applied to an object at rest causes it to accelerate in the direction of the force.

What causes acceleration in newton’s second law?

Acceleration and velocity Newton’s second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate. In the simplest case, a force applied to an object at rest causes it to accelerate in the direction of the force.

How do you find force with mass times acceleration?

For a constant mass, force equals mass times acceleration.”. This is written in mathematical form as F = ma. The product of mass times gravitational acceleration, mg, is known as weight, which is just another kind of force.
