what kind of motion does a constant non-zero net force produce on an object of constant mass 1) constant speed 2) constant acceleration 3)increasing acceleration 4)it depends upon the speed of the object
Answers
Answer:
The velocity vector is constant in magnitude but changing in direction. ... For this reason, it can be safely concluded that an object moving in a circle at constant speed is indeed accelerating. It is accelerating because the direction of the velocity vector is changing.Newton's second law of motion states that acceleration is directly proportional to net force when mass is constant… and that acceleration is inversely proportional to mass when net force is constant… and that net force is directly proportional to mass when acceleration is constant…An object's acceleration is the rate its velocity (speed and direction) changes. Therefore, an object can accelerate even if its speed is constant - if its direction changes. ... Since it travels in a straight line, its direction does not change. Light travels at a constant speed, so its speed never changes, either
Answer:
The correct option is 2) constant acceleration.
Explanation:
- Newton's second law states that motion with a constant acceleration results from a constant force.
- When there are unbalanced forces acting on an object, Newton's second law of motion applies.
- According to the second law, the mass of the item and the net force acting on it both affect how quickly an object accelerates.
- An object's acceleration is directly proportional to the net force applied to it and inversely proportional to its mass.
- An object's acceleration increases as the amount of force exerted on it does.
- A decreasing acceleration is caused by a rise in an object's mass.
There is constant acceleration when there is a net force acting on the object.
