What is critical acceleration?
Critical acceleration is the minimum acceleration required to cause an object to start moving or sliding on a surface. It is the point at which the frictional force between the object and the surface is overcome by the applied force.
Can an internal force cause acceleration in a body?
Yes, an internal force can cause acceleration in a body.
What is the difference between radial and centripetal acceleration?
Radial acceleration is the acceleration towards the center of a circular path, while centripetal acceleration is the acceleration required to keep an object moving in a circular path.
What acceleration will cause a train to travel a distance of 200m in 10 sec if it starts from rest?
The acceleration required for the train to cover a distance of 200m in 10 sec when starting from rest would be 4 m/s^2. This can be calculated using the formula: (a = 2d/t^2), where a is acceleration, d is distance, and t is time.
How is newton related to acceleration and velocity?
Newton's second law of motion mathematically relates acceleration to force as F = ma, where F is the force applied to an object, m is its mass, and a is its acceleration. Acceleration is also related to velocity through the equation a = Δv/t, where Δv is the change in velocity over time t. So, Newton's laws help explain the relationship between acceleration, velocity, and force.
What do you get when you times the objects mass times the acceleration?
You get the force required to cause the given acceleration on the given mass.
Do balanced forces acing on an object cause the object to accelerate?
No. To have an acceleration, an UNBALANCED force is required.
What is critical acceleration?
Critical acceleration is the minimum acceleration required to cause an object to start moving or sliding on a surface. It is the point at which the frictional force between the object and the surface is overcome by the applied force.
Can an internal force cause acceleration in a body?
Yes, an internal force can cause acceleration in a body.
What is the difference between radial and centripetal acceleration?
Radial acceleration is the acceleration towards the center of a circular path, while centripetal acceleration is the acceleration required to keep an object moving in a circular path.
Will leaving a force constant and doubling the mass of an object cause the acceleration to double?
Just the opposite. It will cause the acceleration to drop by 50%.
What acceleration will cause a train to travel a distance of 200m in 10 sec if it starts from rest?
The acceleration required for the train to cover a distance of 200m in 10 sec when starting from rest would be 4 m/s^2. This can be calculated using the formula: (a = 2d/t^2), where a is acceleration, d is distance, and t is time.
Does torque cause angular acceleration?
Yes.
Unbalanced forces on an object cause what?
acceleration

So, Newton's laws help explain the relationship between acceleration, velocity, and force.
What cause acceleration to decrease?
Acceleration can decrease due to friction, air resistance, or an opposing force acting in the opposite direction to the motion. An increase in mass or a decrease in the force applied can also cause acceleration to decrease.
What is the Formula for Force required to accelerate an object to a predetermined speed?
There is no specific force required to accelerate an object to a predetermined speed. A smaller force will produce a smaller acceleration, so it will take longer to reach the desired speed. A larger force will produce a larger acceleration, so the desired speed will be reached sooner. But either the large or the small force, or any other force, will produce an acceleration, and cause the object to reach the specified speed sooner or later.
