The 1 way you can tell an object is in motion is by having a focus point that does not move and watch and see if the object you are looking for is moving. Another way to notice where the object is now, then later, check and see if the object has been moving. lastly, if you are a scientist, you can use telescopes, computers, and the latest gadgets to tell you if an object is in motion.
in terms of speed and direction , in what ways can an object accelerate
An object can accelerate by speeding up (increasing velocity) or by changing direction (experiencing a change in acceleration).
an object can accelerate both up and down
Forces can push or pull an object, change the object's shape or motion, and accelerate an object.
cars and buses
speed up slow down turn
You can accelerate by increasing your speed, boosting your acceleration, or reducing air resistance to minimize drag.
A force can cause the object to accelerate, change its shape, or change its direction of motion.
An object will accelerate in the direction of the net force acting on that object.
No, it is not harder to accelerate a moving object. The initial motion of the object does not affect the force required to accelerate it further. The force required to accelerate an object depends on its mass and the desired acceleration.
Accelerate, motion is generated by applying force to mass.
