Does greater mass in an object have a higher resistance to a change in movement?
Yes, greater mass in an object results in a higher resistance to a change in movement, which is known as inertia. This means that more force is needed to accelerate or decelerate an object with greater mass compared to an object with less mass.
How does gravity and air resistance affect the motion?
Gravity is a force that pulls objects towards the Earth, causing them to accelerate downwards. Air resistance is a force that acts in the opposite direction to the motion of an object, slowing it down. Together, gravity and air resistance can affect the trajectory, speed, and final position of an object in motion.
What causes a falling object to reach terminal velocity?
Terminal velocity occurs when the force of gravity pulling an object down is equal to the air resistance pushing up against it. At this point, the object stops accelerating and maintains a constant velocity. This happens when the drag force on the object becomes large enough to balance out the downward force of gravity.
Why do parachute need large air resistance?
Parachutes need large air resistance in order to slow down the descent of an object. The large surface area of the parachute allows it to catch and trap more air, creating drag that counteracts the force of gravity pulling the object down. This gradual reduction in speed allows for a safe landing.
How does parachutes help to increase air resistance?
Parachutes increase air resistance by capturing a large amount of air in the parachute canopy. This creates drag, which slows down the fall of the object attached to the parachute, allowing for a safer descent. The drag force helps to counteract the force of gravity pulling the object downward.

What is greater the air resistance or the force of gravity?
Mass doesn't affect air resistance directly. Air resistance is affected by the shape of the object. However, other things (shape, density) being equal, an object with a greater mass will have greater air resistance, simply because it is bigger. On the other hand, the larger object will have a smaller ratio of air resistance to mass, since mass will increase with the third power of the diameter (or any linear measurement), while the surface area - which affects air resistance - will only be proportional to the second power of the diameter. This will make a larger object fall faster.
A large vehicle collides with a small ball Which object experiences the greater force?
The small ball will feel the most force. The speed and weight of the car creates a bigger force because there is more energy coming from the car.
What will happen to an object at rest if it is pushed but there is large frictional force acting on the object?
It will stay at rest.
When you apply a tiny force to a tiny object or a large force to a large object you produce?
When you apply a force to a mass you produce acceleration. "Tiny" and "large" are not well defined here, but the basic equation is F = ma, so if the forces are proportional to the masses in each case (for example, a 0.1 N force applied to a 0.1 g object and a 1000 N force applied to a 1000 g object) then you will produce the same acceleration for both objects.
An object with a large surface area has what air resistance?
An object with a large surface area experiences greater air resistance because there is more surface for the air to push against as the object moves. This can slow down the object's motion more significantly compared to an object with a smaller surface area.
When an object is falling its motion is most affected by air resistancce when?
The faster it falls, the more it is affected by air resistance, since air resistance increases with speed. What usually happens in practice is that the object falls faster and faster, and eventually approaches the "terminal velocity" - a speed at which the force of gravity and the force of friction are in balance.
What term used to describe a body's resistance to a change in motion?
Inertia. The larger the mass of the body the larger its inertia, in other words a heavy object would require a large driving force to make it initially move and a large force as well to make it stop moving or change direction.
