Tips and tricks

Which ball gets to the ground first?

Which ball gets to 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.

Which is greater the balls distance or displacement?

Therefore both balls have an equal displacement (same net distance and overall direction of travel) at the instant when they each hit the ground.

Which two balls will arrive at the same time on the ground?

If both are free falling bodies (only gravity is considered ) and are present in vacuum then both will reach the ground at the same time.

When throwing a ball from the ground to a target also on the ground which of these angles will give me the maximum range compared to the rest?

Answer: C Explanation: The maximum range occurs for a launch angle of 45°.

What is the displacement of a ball thrown upward?

Thus, the displacement would have to be 0 meters since a ball thrown into the air would come down and the shortest distance is 0. The definition for displacement can also be represented by s=vi(tf−ti)+0.5a(tf−ti)2.

What is the displacement of a ball?

Displacement is the distance between an object’s initial position and its final position and is usually measured or defined along a straight line. Since this is a calculation that measures distance, the standard unit is the meter (m).

Why do the two balls hit the ground at the same time?

The basic reason the two balls hit the ground at the same time is that the ball is moving faster in the case of the parabolic motion when compared with the straight down motion. The Velocity of the Ball just before it hits the ground: The horizontal velocity V. x=20 m/s is always the in this problem.

What is the velocity of the ball before it hits the ground?

Conclusion: The magnitude of the velocity of the ball is 26.3 m/s for the parabolic motion just before it hits the ground and this greater than the 17.1 m/s for the velocity of the ball that falls

When two balls of different masses are dropped from equal height?

When two balls of different masses are dropped from equal height, they reach the ground at the same time. Can anyone explain this in terms of physics? Newton’s law says that the force F → exercing on an object produces an acceleration a → such as : where m i is the inertial mass of the object.

Why do objects fall at the same speed when dropped?

This is because both experience the same acceleration, g(9.81 m/s2). The acceleration is independent of mass. Thus when they are dropped, they will always maintain the same velocity and travel the same distance (neglecting air resistance of course!) in the same time.
