Give an example of how the force of gravity can change the motion of an object.

A basketball thrown into the air comes back down due to gravity.

A climber moves along a zigzag path up a mountain.

A hockey puck slides across the ice at a constant speed.

A car moves around a roundabout at a constant velocity.

A car brakes suddenly causing it to slow down and eventually come to a stop due to the force of gravity opposing its motion.

A basketball thrown into the air comes back down due to gravity.

A climber moves along a zigzag path up a mountain.

A hockey puck slides across the ice at a constant speed.

A car moves around a roundabout at a constant velocity.
A basketball thrown into the air comes back down due to gravity: As the basketball rises into the air, the force of gravity acts on it, pulling it back towards the ground. This causes the basketball's motion to change from going upwards to downwards, ultimately bringing it back to the ground.

A climber moves along a zigzag path up a mountain: The force of gravity affects the motion of the climber as they navigate the zigzag path. Gravity pulls the climber downwards, exerting a force that must be overcome to continue moving upwards. This can affect the speed and stability of the climber's ascent.

A hockey puck slides across the ice at a constant speed: The force of gravity has a minimal impact on the horizontal motion of the hockey puck since it acts perpendicular to the direction of the puck's motion. As a result, the puck can continue moving at a constant speed across the ice.

A car moves around a roundabout at a constant velocity: Gravity doesn't directly affect the car's motion around the roundabout since it acts perpendicularly to the circular path. The car's constant velocity is maintained due to the balanced forces acting on it, including the centripetal force required to keep it moving in a curved path around the roundabout.
so the answer is?
The example of how the force of gravity can change the motion of an object is when a basketball thrown into the air comes back down due to gravity.
