Why do you warm up before netball?
Netball is started with a Centre pass. Only the centre and the opposing centre are allowed in the centre third. All other players will stand outside the third and wait for the whistle. The ball must be received or touched in the Centre Third. After a goal is scored the defending team will take the centre pass and the game is restarted with the teams taking alternate centre passes. If there is an interception by the opposing team and a goal is scored this team can take the centre pass. So intercepting is important. Netball is started with a Centre pass.

What effect does the mass of the ball have on the period of a simple pendulum What would be the effect of replacing the steel ball with a wooden ball a lead ball and a ping pong ball of the same size?
Replacing the steel ball with a wooden ball would slightly reduce the period, a lead ball would very slightly increase it and a ping pong ball would reduce the period substantially.The period of the pendulum is proportional to the [square root of] the length of the pendulum from the pivot (hanging point) to the centre of the mass of the string and the bob. For a dense material like steel or, even more so, lead, the weight of the string is negligible and the centre of mass of the-string-and-bob will be at the centre of the bob so that the effective length of the pendulum would be from the pivot to the centre of the bob. With a ping pong ball, the mass of the string is no longer quite as insignificant and so the centre of mass of the-string-and-bob will be higher than the centre of the ball and so the effective length of the pendulum will be shorter.
How does a netball game start?
Prior to a game of netball, there will be a toss. The winners of the toss will usually take the centre throw.
