When an object accelerate what can it do?
When an object accelerates it can change its speed or direction of motion. When it accelerates without changing its direction of motion, it can cover any distance in less time.
What caused changes in the object over time?
Depends on what "The Object" is.
What is the term for which velocity changes over time?
If an object's velocity changes over time, it is accelerating.
Describe a situation in which an object accelerates without changing speed?
Acceleration is the rate of change of velocity over time, so velocity must always be changing if the object is accelerating. HOWEVER, you said speed which means only magnitude, not direction. If you stay the same speed, but change direction then you are accelerating. Simple answer: when you are going the same speed in a circle - velocity changes, therefore acceleration changes.
What are three components needed to find an object acceleration?
Using the definition of acceleration as change of speed / time, you basically need to know: * A time interval during which the object accelerates. * The velocity at the beginning of this time interval. * The velocity at the end of this time interval.
Which materials can you use for a 10 kilo newton force?
Anything that weighs 10 kilos. I suggest a bowling ball.A newton is an unit of force, that acts upon an object and causes the acceleration of the object. The acceleration is measured by how fast the speed of the object changes per certain unit of time. One newton is a force that accelerates an object with mass of one kilogram one meter per second.
When an object moves in a circular path it accelerates towards the center of the circle as a result of what?
Well, I was taught that it was centripetal force, but that was a long time ago.
When is an object said to in motion if it changes in time?
Pendulum
What changes over time with density?
density changes when the substance changes.
What are the forces in net force?
Any time an object's velocity changes (the object "accelerates"), that is due to a net force. Here are some examples: * A car speeds up. The force is exerted by the tires, on the road. * A car slows down. The force is exerted by the tires, on the road, or by air resistance. * A car moves in a curve (its velocity changes too, since it changes direction). The force is exerted by the tires, on the road. * A planet moves around the Sun. The velocity changes all the time, since the direction changes. The force is exerted by gravity. * A falling object speeds up. The force is exerted by gravity.
When we can we say that an object is un motion?
That is equivalent to saying that:* The object moves, or * The object's position changes over time
What happens to the velocity of an accelerating object?
It changes over time.
