Explain why friction changes the the Velocity of objects and why friction can make observing Newton's first law of motion difficult?
newtons laws are idealised and don't involve external forces like friction and air resistance
What else can I help you with?
Explain why friction changes the velocity of objects and why friction can make observing newton's first law of motion difficult?
Friction made it difficult to discover newton's first law because under the law an object in motion will remain in motion at a constant velocity unless acted upon by an external force. Friction is an external force that slows objects in motion due to air friction (drag) and rolling resistance, making it appear as though this law is untrue.
If you go sking do you need high or low friction explain?
When skiing, you need low friction to glide smoothly over the snow. High friction would cause you to feel resistance and make it difficult to slide across the surface. A low friction surface allows you to maintain control and move efficiently.
Why it is difficult to move a cycle along a road with its brakes on explain?
Because of the friction between brake pads and rim.Friction applys a forse opposed to the moving direction of rim
Jack is going skiing does he need high or low friction between his skis and the snow?
low friction
Explain the circumstances when the acceleration and the velocity of car are parallel?
when velocity of a car is increasing then velocity and acceleration are parallel to each other.
Explain why you don't do any work when you carry an object at a constant velocity?
When carrying an object at a constant velocity, no work is being done because work is a force applied over a distance in the direction of the force. Since the object is moving at a constant velocity, the force applied to overcome gravity and friction is equal to the force of gravity and friction acting in the opposite direction, resulting in a net force of zero. Therefore, no work is being done on the object.
Explain how distance time and velocity are related to each other?
They are related through the formula distance = time x velocity (assuming constant velocity).
Explain how friction is involved in energy transformation?
Friction creates heat - heat travels by convection, conduction or radiation.
Explain whether troubleshooting in ring topology is easy or difficult?
difficult
Explain why observing using only your senses can be misleading?
Observing using only your senses can be misleading because our senses can be limited and subjective. Our perceptions can be influenced by factors such as biases, emotions, and past experiences, leading us to misinterpret what we observe. Additionally, some phenomena are not directly observable by our senses, making it difficult to fully understand the complexities of a situation.
Does the movement of woodpecker involve friction force explain?
Every movement you make requires friction. When you walk, it requires friction. When a woodpecker is pecking a hole in a tree, it requires friction for him to keep his toes in the tree- static friction, to be specific. Hope that helped!
How does physics relate to friction?
physics explain what needs to exist or happen to cause friction and so provide ways to measure (control) frictions.
