Constant Speed VS Constant Velocity

A person jogs on a treadmill set at a constant speed of 10 kilometers per hour. The treadmill maintains a consistent pace, and the person continues jogging without speeding up or slowing down. Is this scenario an example of:

• A person running at a variable speed.

• A person running with constant speed.

• A person accelerating on a treadmill.

• A person running with constant velocity.

A car travels along a straight highway at a speed of 70 miles per hour for an extended period without changing its speed. Is this scenario an example of:

• A car accelerating on a straight road.

• A car moving with constant speed.

• A car moving with constant velocity.

• A car decelerating on a straight road.

An sprinter runs at 15 m/s at all times around a circular track. Is this scenario an example of:

• An object accelerating in a straight line.

• An object moving with constant speed only.

• An object decelerating in a circle.

• An object moving with constant velocity.

A skier descends down a slope at 20 kilometers per hour. The skier maintains both speed and direction, adapting to the curvature of the slope. Is this scenario an example of:

• A skier accelerating down a slope.

• A skier moving with constant speed.

• A skier decelerating on a straight path.

• A skier moving with constant velocity.

A cyclist rides at a constant speed of 25 kilometers per hour around a circular track. Is this scenario an example of:

• A cyclist accelerating in a straight line.

• A cyclist moving with constant speed only.

• A cyclist decelerating in a circle.

• A cyclist moving with constant velocity.

A boat steers to the right at a speed of 30 knots for an extended period without changing its speed. Is this scenario an example of:

• A boat accelerating on a straight path.

• A boat moving with constant speed only.

• A boat moving with constant velocity.

• A boat decelerating on a straight path.

A satellite orbits the Earth at a constant velocity of 25,000 kilometers per hour. The satellite moves at a consistent speed while continuously revolving around the planet. Is this scenario an example of:

• A satellite accelerating in space.

• A satellite moving with constant speed only.

• A satellite decelerating in orbit.

• A satellite moving with constant velocity.
