Friction is a force. A resistance force that tries to slow down and stop objects in motion. The difference between friction and air resistance is that friction acts on surfaces. For example, if I were skateboarding on a rough surface, more friction would occur so I would travel slower. If I were skareboarding on ice, I would go faster because there is much less friction to slow me down. Hope that helps:)
Answer:
If a car is moving at a <em><u>constant velocity of 10 m/s,</u></em> there will be no change in the velocity per time.
Acceleration is the rate of change of velocity
Acceleration=(Final velocity-Initial velocity)/Time
Acceleration=(10m/s-10m/s)/Time= <em><u>0 m/s²</u></em>
<h3>★ <u>0 m/s²</u> is the right answer. </h3>
Answer:
<h3>Following are the properties and characteristics of the glass.</h3>
<h3>Hardness and Brittleness. It is a hard material as it has great impact resistance against applied load.</h3>
- Weather Resistance.
- Insulation.
- Chemical Resistance.
- Colour and Shape Varieties.
- Transparency.
- Fire Resistant Glazing.
- Property Modification.
We will solve this question using the second law of motion which states that force is directly equal to the product of mass and acceleration.
Where,
- F is force
- m is mass
- a is acceleration
In our case,
- F = ?
- m = 2500 kg
- a = 20m/s
<em>Thus, The force of 50000 Newton is required to accelerate a car of 2500 kg...~</em>
