If a 90 kg weightlifter exerts a 1000 N force upwards against a 50 kg barbell, the NET vertical force acting on the barbell is 1000 N. It does not matter how heavy the weightlifter or the barbell might be.

Why does The smoke from a bonfire rises upwards?

The smoke from a bonfire rises upwards due to the difference in temperature between the smoke and the surrounding air. As the hot smoke rises, it mixes with the cooler surrounding air, creating vertical movement. Additionally, the heat from the fire creates a convection current that helps propel the smoke upwards.


What is the force that gives a thrown ball its vertical movement?

Gravity is the force that gives a thrown ball its vertical movement. As the ball is thrown upwards, gravity acts on it, pulling it back down towards the ground. The vertical movement of the ball is a result of the interaction between the force of the throw and the force of gravity.


How can one determine the vertical velocity of a projectile?

To determine the vertical velocity of a projectile, you can use the formula: vertical velocity initial vertical velocity (acceleration due to gravity x time). The initial vertical velocity is the speed at which the projectile is launched upwards or downwards. Acceleration due to gravity is typically -9.8 m/s2 (negative because it acts downwards). Time is the duration for which the projectile has been in motion. By plugging in these values, you can calculate the vertical velocity of the projectile.


What is the definition of vertical velocity?

Vertical means up and down; so the vertical velocity is an indication of how quickly an object is rising or falling. If the object is moving at an angle (such as an airplane taking off or landing) then it would be more accurate to call it the vertical component of the object's velocity.


If a 100 kg man hangs from a 50 kg barbell while another man pulls him and the barbell upwards with a force of 1700 N what is the approximate net force of this system?

The net force is the sum of all forces acting on the system. The force of gravity on the man and barbell is approximately 1500 N (100 kg * 9.81 m/s^2 + 50 kg * 9.81 m/s^2). The force exerted by the man pulling is 1700 N. Therefore, the net force is 200 N (1700 N - 1500 N).

If an unstable air mass is forced upwards what type clouds can be expected?

If an unstable air mass is forced upwards, you can expect cumulonimbus clouds to form. These clouds are associated with thunderstorms and can bring heavy rain, lightning, and strong winds. The instability in the air mass allows for rapid vertical development of these clouds.

It is usually a linear measure in the vertical direction, measured downwards. If measured upwards, the same measure could be called a height.
