How far will the cannonball travel horizontally?
770 m.
What happens when you throw a ball horizontally?
The time required for initially horizontal projectile motion to occur is the same as the time required for the object to fall to its final height. Thus, a ball thrown horizontally will reach the ground at the same time as a ball dropped from the same height.
What happens to the motion of ball if you throw the ball at an angle to the vertical?
If we stand at the edge of the roof of the Science Building and throw a ball up at an angle, it moves up and then down vertically while it moves horizontally. This is projectile motion.
What ball reaches the ground first?
As gravity is the only force in both cases, both balls will hit the ground at the same time. When you throw a ball, we are assuming that you are throwing it horizontally. This means you are giving the ball only horizontal velocity.
Why do both balls hit the ground at the same time?
When you drop a ball (or anything) it falls down. Gravity causes everything to fall at the same speed. This is why balls that weigh different amounts hit the ground at the same time. Gravity is the force acting in a downwards direction, but air resistance acts in an upwards direction.
When a ball is thrown horizontally and another is dropped which will be faster?
Same was for the other ball(it had different horizontal velocity). Now the acceleration on both the balls was same so the time taken for them to reach the ground should be same. Hence same vertical speed. Horizontal speed is obvious that ball thrown horizontally will be faster.
Why does something drop when I throw it up?
When you throw something upwards it loses speed as it moves further away from the earth, due to the earths gravitational pull. ‘Infinitely’ far from the earth the earths gravitational pull is zero, and ‘thrown’ objects no longer slow down as they move away from the earth.
Is there acceleration in free fall?
Analyzing motion for objects in freefall Freefall is a special case of motion with constant acceleration, because acceleration due to gravity is always constant and downward. This is true even when an object is thrown upward or has zero velocity.
Does drag force increase with speed?
Drag increases with speed (v). An object that is stationary with respect to the fluid will certainly not experience any drag force. Start moving and a resistive force will arise. Get moving faster and surely the resistive force will be greater.
Does drag slow you down?
Friction drag: It occurs next to the surface of an object. Form drag: A force affected by the shape of the body. Air flowing past an object breaks away from the surface to form little swirling pockets of air called eddies. These take energy from the object and slow it down.
