An object is traveling at constant velocity. A non-zero resultant force starts acting on it. State two ways in which this force can change the motion of the object.
State one other effect (not related to motion) that a force can have on an object.
A speedboat has a mass of 800 kg. The speedboat, initially at rest, is accelerated in a straight line by a constant resultant force of 1200 N until it reaches a speed of 24 m/s.
Calculate the average acceleration of the speedboat.
A speedboat has a mass of 800 kg. The speedboat, initially at rest, is accelerated in a straight line by a constant resultant force of 1200 N until it reaches a speed of 24 m/s.
Calculate the time for which this resultant force is applied.
A speedboat has a mass of 800 kg. The speedboat, initially at rest, is accelerated in a straight line by a constant resultant force of 1200 N until it reaches a speed of 24 m/s.
State the name of a force which opposes the motion of the speedboat through the water.
