What type of force accelerates an object?
It depends what the situation is. If an object is falling, the weight of the object, which is determined by the object's mass and the gravity, is the force causing it to accelerate. If you're talking about a box being pushed, you could have a person pushing it, which causes it to accelerate, but you also must take into account the force of friction combatting the applied force.
Why does the y-value of the velocity vs. time graph stay constant?
You're looking at one specific velocity/time graph that we can't see. From your description, we can tell that the object whose motion is described by that graph is moving at a constant rate of speed ... which is exactly what you just said while looking at the graph.
What causes change in velocity?
If an object's velocity changes -- if its speed increases or decreases or if its direction changes -- that means it has accelerated. For an object to accelerate, the sum of the forces acting upon it must be non-zero. So, in other words, forcechanges an object's velocity.
What is newtons first law of motion and what does it state?
The first law deals with forces and changes in velocity. For just a moment, let us imagine that you can apply only one force to an object. That is, you could choose push the object to the right or you could choose to push it to the left, but not to the left and right at the same time, and also not up and to the right at the same time, and so on. Under these conditions the first law says that if an object is not pushed or pulled upon, its velocity will naturally remain constant. This means that if an object is moving along, untouched by a force of any kind, it will continue to move along in a perfectly straight line at a constant speed.
What does it mean when final and initial velocity are the same?
When the final and initial velocities are the same, it means that the object's velocity hasn't changed over time. This could indicate that the object is at rest or moving at a constant speed in a straight line.
How could an object accelerate was still traveling at a constant speed?
An object can accelerate while still traveling at a constant speed if it changes direction. Acceleration is the rate of change of velocity, so even if the speed remains constant, a change in direction would still require acceleration.
Why does a car traveling at constant speed can accelerate while a car at constant velocity connot?
The question is inherantly flawed. A car traveling at a constant speed cannot accelerate, if it could it's speed would not be constant. "Constant speed" means that speed is not increasing or decreasing but remain consistent over time. For example, if you cover 10 feet during each second, your speed is constant. "Constant velocity" implies constant speed, but it has an additional constraint: you can't change your direction. If you travel constantly at 10 feet per second in a straight line, then your speed is constant and your velocity is constant. But if you travel constantly at 10 feet per second in a wiggly line (or a circle, or anything not straight), then your speed is constant but your velocity is NOT constant. If you travel at a constant speed but change direction, velocity is changed. Or if you travel in the same direction but change the speed, velocity is changed. Average speed is is easier: distance/time So, your question should read: Why can a car traveling at an average speed accelerate, but a car traveling at constant speed cannot? Or Why am I asking the wrong questions?
Can a body have a constant velocity and still be accelerating?
No. Acceleration is defined as the rate of change of velocity. If velocity is constant, then its rate of change is zero. --------------------------------------------------------------------------- Another contributor obfuscated: If we were to get really picky with our vectors we could say that an object could have constant velocity in the x-y plane and still accelerate in the z-axis. Also a system of objects could have a net-velocity in 3-D space and still have a radial acceleration. A solar system traveling through space at constant velocity will have a radial acceleration, for each component part of the system, around the gravitational center of mass of the system.
What happens when unbalenced force acts on an object?
When an unbalanced force acts on an object, it causes the object to accelerate in the direction of the force. This acceleration could result in the object moving faster, slowing down, or changing direction. The object will continue to accelerate as long as the unbalanced force is applied.
If the net force on an object is zero then the object is?
Not accelerating. It could be stationary or moving at a constant speed.
What is single number without a variable?
Constant, perhaps scalar constant. Since you could have a constant vector or other object, as well.
If an unbalanced force acts on an object what could change?
If an unbalanced force acts on an object, it could cause the object to accelerate in the direction of the force, change its speed or direction of motion, or cause the object's shape to deform if the force is strong enough.
Why must a force be exerted in an object ti change its velocity?
We know that that is the way our Universe works; WHY the Universe was designed that way, or why it happens to be that way, is normally not known.In this case, with a different law for velocity, lots of the physics we know would be drastically different - for example, conservation of energy, conservation of momentum, and conservation of angular momentum could all be violated.
The net force of an object is zero can you conclude that the object is at rest?
You can't. The net force simply means that the acceleration is zero. It could be at rest, or the object could be moving at a constant velocity.
How would you find the mass of an object if there were no gravitational force?
Mass is defined as resistance to acceleration, so one could measure how much force is needed to accelerate the object.
If an object has zero acceleration what two things could be true about its velocity?
The velocity does not change direction or magnitude. The object 1) may not be moving, or it 2) may be moving at a constant velocity. In the case of the latter, that means it's moving in the same direction and at a constant speed.
What path might an object take that involves changing its velocity?
An object might follow a curved path or change direction to alter its velocity. This could happen due to external forces like gravity, friction, or applied forces. The object could accelerate, decelerate, or change direction to adjust its velocity.
