Summary: Physics: golfers hit the ball from the slope h=20m above the horizontal ground, and the ball falls into the slope l=60m awayFrom the free fall formula h=1/2 *g*t^2, h= (one-half) multiplied by (g) mul
Physics: golfers hit the ball from the slope h=20m above the horizontal ground, and the ball falls into the slope l=60m away
From the free fall formula h=1/2 *g*t^2, h= (one-half) multiplied by (g) multiplied by (T square) 20=0.5*10* (T square), t=2s, because the golf ball makes a flat throwTwo physics problems in senior one, solve ah ah ah ah ah ah ah ah ah ah
1 solution: in the vertical direction, h=5m, from h=1/2gt^2, t=1s in the horizontal direction, s=v in the horizontal direction, t = V in the horizontal direction, V in the horizontal direction =20m/s. 2 solution divides the motion of the ship into the direction perpendicular to the current and the direction along the currentPhysical problems
Inertia force and friction force don't form a couple on a straight line. What's left is to analyze it by yourself. Draw a picture and everything will come out. Is it because the flute becomes longerExplain why golf balls have rough surfaces with physical knowledge
Aerodynamicists divide this force into two parts: lift and drag. The action direction of drag is opposite to the direction of motion, while the action direction of lift is upward. Small pits on the surface of golf balls can reduce air resistance and increase the lift of the ball. A high-speed golf ball will have a high-pressure area in front of itExplain why the surface of golf balls is rough and small with physical knowledge
Then, why do hollows fly far away. Most golf balls have 300 to 500 small pits There is also a longer interpretation version. A spinning ball with an uneven surface? The smooth surface originally thought that the air resistance was small, and it seemed that it would fly farther. How could it be the opposite, and the action direction of lift was upwardAstronauts play golf in space and hit 1billion miles. What is junior high school physics knowledge about
Astronauts play floating ball in space. The physical concepts involved in this are as follows. First, astronauts a re in space. If they are in space, it can be considered that space is in a vacuum. If they can play golf in a hurry, golf should first be prohibited fr om being released by herPhysics problems table tennis, bowling and other surfaces are smooth, why the surface of golf
When there is no blowing, the equal arm lever keeps balanced, indicating that the gravity of a and B balls is equal. When the wind blows at the same speed, the force of a and B balls is analyzed. Both balls are affected by two forces in the vertical direction, namely, the downward gravity and the upward wind force (the magnitude is equal to the resistance of the ball)Ask a high school physics problem, wait
1. First of all, we should understand that the object does an oblique upward throwing motion. A: 2.5 seconds at the top, 5 seconds back to the ground. 2．B：. As shown in the figure, at 2.5s, a degree of 19 indicates that the object is at the highest point. At this time: v0y gt=0, v0x=19 H = (0 + v0y) T1 / 2 = gt1t1 /
Physics why golf balls fly farther than smooth balls of the same mass
Therefore, how to reduce the air resistance becomes the key. When golfers hit the ball, each ball obtains a backward rotation force, which is closely related to these dents, as if a thick air pillow was formed under the ball. A golf ball will fly at high speed after being hit, and there will be a high-pressure area in front of itConsult high school physics problems and experts, and expect to have an analysis process
Due to the constant horizontal wind force, the ball is hit out and makes a uniform deceleration movement in the horizontal direction
