... To give a 15 kg child a ride, two teenagers pull on a 3.4 kg sled with ropes, as indicated in Figure 5-26. Both teenagers pull with a force of F = 65 N at an angle of 35° relative to the forward direction, which is the direction of motion. In addition, the snow exerts a retarding force on the sled t ...

... Gravity's pull on objects is a constant here on Earth (an object will fall at a constant acceleration of 9.8 or 10 m/s2) and it always pulls toward the center of the planet (Note: Gravity decreases as you move far away from the surface of the planet.). We can see how quickly an object gains speed a ...

Circular motion
... An object that moves in a circle is accelerating even if its speed is constant. For an object undergoing uniform circular motion, the magnitude of the velocity (speed) remains constant, but the direction of the velocity is continually changing. Since acceleration is defined as the rate of change i ...
