Because of air friction, the more physical space that an object takes up, the more power the object will need to move, this is because of the way air forces friction onto the moving object, therefore a small car/vehicle will have less air friction than a larger vehicle with more surface area
Momentum = Mass x Velocity
So, more mass equals more momentum.
Basically correct, except for the wording. It should be: "... the harder it is to change its velocity".
yes because of Newton's law F=ma. If you increase mass, you have to increase force to achive the same acceleration.
As mass increases acceleration decreases.
force=mass*acceleration Therefore acceleration = force/mass This means you can change an objects acceleration in two ways, either by applying a force to the object (for example pushing a shopping trolly). You can also change the acceleration of an object by changing the mass of the object (putting shopping in the shopping trolly)
Velocity can only change if the object experiences an acceleration. Acceleration can only change if either the Force on the object increases, or the Mass of the object decreases.
Acceleration is "force divided by mass" or "change in velocity with respect to change in time".
Force = Mass * Acceleration or Acceleration = Force / MassThe Mass is the mass of the object and the Acceleration is the change of speed of the object due to the Force.
the acceleration of the object.
Decrease the mass, and change the force.
We have this very important law in physics called: NET FORCE = m * a m = mass a = acceleration The NET force would create an acceleration... and that will change the velocity of the object.
Force equals mass times acceleration. To change a speed, you must apply some force (either positive or negative) to give the object some acceleration. How quickly the object's speed changes will correspond to the force given divided by the mass of the object. (ie, the acceleration)

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
