ReneTwo factors that can cause a change in velocity are acceleration, which is the rate of change of velocity, and the application of an external force. An increase in acceleration will cause a greater change in velocity over time, while the direction and magnitude of an external force can also affect the velocity of an object.

When you want to change an object's velocity you have to overcome?
When you want to change an object's velocity, you have to overcome its inertia. Inertia is the tendency of an object to resist changes in its motion. By applying a force to the object, you can overcome this resistance and change its velocity.
How do you find change in velocity?
Change in velocity is found by subtracting the initial velocity from the final velocity. Mathematically, it can be expressed as Δv = vf - vi, where Δv is the change in velocity, vf is the final velocity, and vi is the initial velocity.
What the 2 factors affect the kinetic energy of an object?
The two factors that affect the kinetic energy of an object are its mass and its velocity. The kinetic energy of an object increases with both mass and velocity.
What are the 2 factors that effect an objects momentum?
The two factors that affect an object's momentum are its mass and its velocity. Momentum is calculated as the product of an object's mass and its velocity, so changes in either of these factors will impact the momentum of the object.
What is the expression for average acceleration?
The expression for average acceleration is given by the change in velocity divided by the time taken for that change. It can be written as: average acceleration (a) = (final velocity - initial velocity) / time.
