What happens when projectile moves up?
As the projectile moves upwards it goes against gravity, and therefore the velocity begins to decelerate. Eventually the vertical velocity will reach zero, and the projectile is accelerated downward under gravity immediately. Once the projectile reaches its maximum height, it begins to accelerate downward.
What are the 2 forces acting on a projectile?
The forces acting on projectile motion, excluding the force that get the projectile in motion, are gravity and drag due to friction with the air, although often the latter can be ignored safely.
Does lift affect the speed of a projectile?
Because the lift force is perpendicular to the velocity of the object, lift can have no effect on the magnitude of velocity. The magnitude of velocity is also known as speed, so (D) is correct.
What is projectile motion caused by?
A projectile is any object that once projected or dropped continues in motion by its own inertia and is influenced only by the downward force of gravity. By definition, a projectile has a single force that acts upon it – the force of gravity.
What is projectile in physics?
A projectile is an object upon which the only force acting is gravity. A projectile is any object that once projected or dropped continues in motion by its own inertia and is influenced only by the downward force of gravity. By definition, a projectile has a single force that acts upon it – the force of gravity.
What force acts on a projectile?
gravity
The only force acting upon a projectile is gravity!
Does drag affect projectile motion?
Objects moving through air are slowed down due to air resistance, sometimes called drag. This air resistance affects a spacecraft when it re-enters the Earth’s atmosphere but also the path of a projectile such as a bullet or a ball. The maximum height, the range and the velocity of the projectile are all reduced.
