What are the forces acting on a race car while it starts to move faster? What are the forces acting on a racing car while it slows down around a turn? What are all the forces acting upon a package within a car when a driver slams on the brakes?
A crate resting on an inclined plane is in a state of static equilibrium i.e. all the forces acting on the crate are in balance. Using a free-body diagram and by applying our knowledge of friction in practice, we identify the forces acting on the crate. ...
Free body diagrams show all the forces acting on an object. For example, a skydiver's weight acts on him by pulling him down towards the ground- air resistance (drag) acts upon him, in the opposite direction to his motion. What do the sizes of the arrows show?
Homework Statement An 80 kg skydiver jumps from an altitude of 1000m and opens his chute at 200m (a) The total retarding force on the diver is a constant...
Your body feels acceleration in a funny way. When a coaster car is speeding up, the actual force acting on you is the seat pushing your body forward. But, because of your body's inertia, you feel a force in front of you, pushing you into the seat. You always feel the push of acce...
A car was initially at rest at the origin. It started to accelerate in a straight line as a result of a force acting on it, given byFc=KtF_{c}=KtFc=Kt. If the mass of the car ismcm_{c}mc, find as a function of time its velocityvcv_{c}...
The Terminal Velocity of a falling object depends on their shape and area The accelerating force acting on all falling objects is gravity and it would make them all fall at the same rate if it wasn’t for air resistance This means that 2 objects of different mass but the same shape and ...
For instance, consider a skydiver falling through air under the influence of gravity. The two forces acting on him are the force of gravity and the drag force (ignoring the buoyant force). The downward force of gravity remains constant regardless of the velocity at which the person is moving...

A force is a push or pull that one object exerts on another.It tends to produce motion, and stops or tends to stop motion.Types of forces Nature of forces Contact force The push experienced when two objects are pressed together Weight The gravitational pull of the Earth on an object Fricti...
