Important Questions on Dynamics: Explaining Motion
Name the force: the force in a string that is holding up an apple
Imagine throwing a shuttlecock straight up in the air. Air resistance is more important for shuttlecocks than for a tennis ball. Air resistance always acts in the opposite direction to the velocity of an object. Draw diagrams to show the two forces, weight and air resistance, acting on the shuttlecock: As it moves upwards
Imagine throwing a shuttlecock straight up in the air. Air resistance is more important for shuttlecocks than for a tennis ball. Air resistance always acts in the opposite direction to the velocity of an object. Draw diagrams to show the two forces, weight and air resistance, acting on the shuttlecock: As it falls back downwards.
Describe one 'Newton's third law pair' of forces involved in the following situations. In each case, state the object that each force acts on, the type of force and the direction of the force. You step on someone's toe.
Describe one 'Newton's third law pair' of forces involved in the following situations. In each case, state the object that each force acts on, the type of force and the direction of the force.
(b) A car hits a brick wall and comes to rest.
Describe one 'Newton's third law pair' of forces involved in the following situations. In each case, state the object that each force acts on, the type of force and the direction of the force.
