What are the 3 things that can change velocity?
There is basically only ONE thing that can make a velocity change, and that is a force acting on an object.
3 ways an object can accelerate?
1.speed up 2.slow down 3. turn
A constant 9.0-N net force acts for 2.0 s on a 6.0-kg object What is the object's change of velocity?
F = M AM = object's massA = its accelerationA = F/MAcceleration of this object = 9/6 = 1.5 meters per second2In 2 seconds, the component of its its velocity in the direction of the net force increasesby (1.5 x 2) = 3 meters per second.
What 3 things can happen when an object accelerates?
The object's speed can increase, leading to a higher rate of motion. The object's direction of motion can change, causing it to deviate from its original path. The object can experience a change in velocity, which is a combination of speed and direction.
What are 3 ways that objects accelerate?
Due to a force acting on the object, such as gravity pulling an object downward. When the direction of the object's velocity changes, as in the case of circular motion. During collisions or interactions with other objects that transfer momentum to the object.

When does an object undergoes acceleration?
Acceleration is the change in velocity of an object over time. Take note that velocity is a vector quantity which means that it has magnitude and direction...Thus...An object undergoes acceleration when:1. there is a change in the magnitude of the velocity (speed) of an object.2. there is a change in direction of an object.3. it changes both in direction and magnitude.
What 2 ways causes an object's velocity to change?
If an object's speed changes, or it heads off in a new direction, its velocity has changed. Because of friction and gravity 1. acceleration 2. deceleration 3. change of direction

3 ways to accelerate?
To change the acceleration of a car: speed up, slow down or turn. Acceleration is any change in velocity. Velocity is "how fast" and in "what direction". To speed up is to accelerate (increase the velocity). To slow down is to deaccelerate (decrease the velocity) To turn is also a form of acceleration (changes the direction of the velocity).
How velocity of an object can affect the work done by the object when moving up and inclined?
work = force * distance and force = mass * acceleration and acceleration = change in velosity/change in time so work = mass * acceleration * distance , as a result work = mass * change in velosity/change in time * distance, hence the velocity of the object affected by : 1.mass of the object. 2. gravitational acceleration which reduces the speed of the object when go up and increases the speed of the object when it come down.. 3. look at the rules etc........thx..............with best regards
Relationship between acceleration and momentum?
No. Momentum is defined as mass times velocity, acceleration is the rate of change of velocity. To be more accurate, velocity is a vector quantity, it has both magnitude and direction. Momentum is therefore also a vector quantity in the direction of the velocity with magnitude equal to the mass times the magnitude of the velocity: 1) p = mv Acceleration is also a vector quantity and in the direction of the change in velocity direction and represents the rate of change of velocity: 2) a = dv/dt Force is defined as the rate of change of momentum, and is therefore also a vector in the direction of the momentum change: 3) F = dp/dt Substituting 1) in 3) we get: 4) F = m(dv/dt) And since 2) defines dv/dt as acceleration we get: 5) F = ma In other words, force is mass times acceleration. Note: The assumption above is that mass remains constant. This is an approximation that remains true only for slow speeds in comparison with the speed of light. These equations do not hold when approaching the speed of light as mass increases, and in fact makes it impossible to actually accelerate something to the speed of light.
An object goes from a speed of 9ms to a total stop in 3 s. what is the objects acceleration?
The object's acceleration is -3 m/s^2 (negative because it is decelerating), calculated by dividing the change in velocity (9 m/s) by the time taken (3 s). The negative sign indicates the direction of the acceleration is opposite to the initial velocity.
What describes how fast an object is moving and in what dirrection?
The maximum speed of any object is hardly equal to speed of light which is 3*10^8 approximately.
