do heavier objects accelerate faster?

Heavier things have a greater gravitational force AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass. ... If the car drives faster, the air resistance force gets larger.

First, time appears to move slower near massive objects because the object's gravitational force bends space-time. Public Domain The phenomenon is called "gravitational time dilation." In a nutshell it just means time moves slower as gravity increases.

An object, usually a metal ball for which air resistance is negligible, is dropped and the time it takes to fall a known distance is measured. ... Velocity is seen to increase linearly with time while displacement increases with time squared. Acceleration is a constant and is equal to gravitational acceleration.

There are two important motion characteristics that are true of free-falling objects: Free-falling objects do not encounter air resistance. All free-falling objects (on Earth) accelerate downwards at a rate of 9.8 m/s/s (often approximated as 10 m/s/s for back-of-the-envelope calculations)

Force is a push or pull that an object can exert on other objects. Acceleration is the rate of change of an object's speed. If an object has mass, and is accelerating through space, then the object can exert a force. This principle is described by Newton's second law of motion.

In other words, the faster an object moves, the greater its mass. ... If an object tries to travel 186,000 miles per second, its mass becomes infinite, and so does the energy required to move it. For this reason, no normal object can travel as fast or faster than the speed of light.

As force increases acceleration increases. Acceleration is indirectly proportional to mass (force ~ 1/mass) As mass increases acceleration slows.

Two major factors, mass and distance, affect the strength of gravitational force on an object.

The faster an object moves, the more kinetic energy it has. The more mass an object has, the more kinetic energy it has.

states that the acceleration of an object increases with increased force and decreases with increased mass. ... Notice how mass and force affect acceleration. Newton's second law. The acceleration of an object increases with increased force, decreases with increased mass, and is in the same direction as the force.

So the car would have 16 times the power to weight ratio of the truck, therefore can accelerate much faster. Petrol engines fitted to most cars can rev twice as fast as diesel engines fitted to trucks, so a car can continue to accelerate well beyond the top speed of the truck. Cars are more aerodynamic than trucks.

An object with negative acceleration could be speeding up, and an object with positive acceleration could be slowing down. How is this so? Consider the fact that acceleration is a vector that points in the same direction as the change in velocity.

Inertial mass is a measure of how fast an object accelerates--given the same force, increasing the inertial mass implies decreasing acceleration. The simplest way to state the equivalence principle is this: inertial mass and gravitational mass are the same thing.

That speed is called the escape velocity . where G is the gravitational constant, M is the object's mass, and R is its radius. Note that for a given mass, as R gets smaller, V will get larger. ... The mass doesn't affect the escape velocity.

When we look at the relationship between power and velocity on the graph below, we see a different shaped curve. So, if we move fast we have increased power because we are doing things in less time. However, there is a trade off in that as we speed up more and more we produce less force, which means less power again.

Although the gravitational force the Earth exerts on the objects is different, their masses are just as different, so the effect we observe (acceleration) is the same for each. The Earth's gravitational force accelerates objects when they fall. It constantly pulls, and the objects constantly speed up.

For collisions between equal-mass objects, each object experiences the same acceleration.
