More mass means more inertia - more difficult to change the velocity. Newton's Second Law: force = mass x acceleration, means that for more mass, you need more force to get the same acceleration. Alternatively (if you save for acceleration), if you increase the mass, the same force will produce less acceleration.
Note: It is the MASS of the object, not its WEIGHT, that is relevant here. On Earth, though, weight is proportional to the mass.

Why do lighter objects fall slower than heavy objects?
Lighter objects fall slower than heavier objects because they have less mass, which results in less gravitational force acting on them. This means they experience less acceleration and take longer to reach the ground compared to heavier objects. The acceleration due to gravity is the same for both objects, but the heavier object requires more force to overcome its weight and accelerate at the same rate.
Does the weight of the car affect the speed of the car?
Yes...a heavy car will accelerate slower, take longer to stop and ultimately have a lower top speed then if it were lighter. The first two are correct but the last is wrong. The simple fact that the car IS heavier means there will be more kinetic energy achieved over a longer time to very fast top speed usually occur in heavier equipped cars with the correct type of engine. The fastest cars (the speed record holders) start slowly but gain very fast speed weigh in and more than 15,000 lbs. That is 3 to 5 times heavier than the typical car.
Does it take more force to move heavier objects than lighter objects?
All other factors being Equal, Yes. This is even true in Space where the objects 'may' be unaffected by Gravity and WEIGH Zero. The critical factor here is MASS, which we commonly call WEIGHT on the Earth. The MASS of an Object does not change based on its POSITION. The WEIGHT of an object varies based on its Position relative to a Gravitational body, such as the Earth.
Why do trains take so long to stop?
Trains take a long time to stop because of their size and weight. The momentum of a moving train is very high, so it requires a lot of force to slow down and come to a complete stop. Additionally, trains rely on friction between the wheels and the tracks to stop, which can take a longer distance compared to other vehicles.
Is it true the effects pf kinetic energy the slower and objecg goes the longer that it will take to bring that objecg to a stop?
Yes, that is true. The kinetic energy of an object is directly proportional to its speed, so the slower an object goes, the less kinetic energy it has. This means it will take longer to bring the object to a stop compared to if it were traveling faster.
Do large trucks take longer to stop than a car traveling at the same speed?
Yes. Because the truck is heavier.
Do heavier cars take longer to stop?
Yes, heavier cars generally take longer to stop compared to lighter cars, assuming all other factors are equal. This is due to the greater momentum that heavier vehicles possess, which requires more force to decelerate. Additionally, heavier cars may have larger braking distances because of the increased mass that needs to be slowed down. However, factors such as brake system efficiency, tire grip, and road conditions also play significant roles in stopping distance.

What is the orbit time around the earth?
Near the surface of the Earth, the time for an orbit is about one and a half hours. As objects (satellites) get farther, they would take longer for an orbit.Near the surface of the Earth, the time for an orbit is about one and a half hours.

Does speeding have an effect on braking distance?
Yes, the faster you are moving the longer it will take to stop.

Why does an automatic with ABS take longer to stop when braking?
The wheels do not lock up with abs. This gives you more control to steer the vehicle out of danger but it takes longer to stop.
