What force changes the speed of a moving object?
A force that is applied in the direction of motion can change the speed of a moving object. This force can either increase or decrease the speed, depending on its magnitude and direction. Examples of such forces include friction, air resistance, and propulsion forces.
When the Lorry is traveling at a constant speed what forces are balanced?
When a lorry is traveling at a constant speed, the driving force from the engine is balanced by the resisting forces such as air resistance, friction between the tires and the road, and other resistance forces. This balance of forces allows the lorry to maintain its constant speed.
What happens to to the speed of a motor if i increase or decrease the number of bulbs in a circit?
If you increase the number of bulbs in a circuit, the resistance in the circuit will increase, causing the motor's speed to decrease. If you decrease the number of bulbs, the resistance in the circuit will decrease, causing the motor's speed to increase.
Why does weight increase as speed increases?
Weight does not actually increase as speed increases. However, the sensation of weight can appear greater when moving faster due to the additional forces acting on the body, such as air resistance or acceleration forces. This can give the perception of increased weight, even though the actual weight of the object or person remains the same.
What types of forces cause objects to accelerate?
The forces that cause objects to accelerate include gravity, friction, air resistance, tension, normal force, and applied force. These forces can either increase or decrease an object's speed or change its direction of motion.
How does water or air resistance against an object increase speed?
It doesn't increase speed. The word resistance means to resist. In other words it decreases speed.

What can increase the speed of object?
Increasing the force applied to the object or reducing the air resistance can increase the speed of an object. Additionally, decreasing the mass of the object can also help increase its speed.
What causes speed to decrease?
Speed can decrease due to forces like friction, air resistance, or gravity acting in the opposite direction to the motion. Additionally, factors like an increase in mass or a change in the surface conditions can also cause speed to decrease.
What three forces affect speed?
The three forces that affect speed are thrust (what propels the object forward), surface area (the smoothness and amount of area that comes in contact with the air, which can also be called friction), and drag.
Are there any forces when a car goes at a constant speed?
forward thrust from the driving wheels, which is equal ( and opposite ) to the frictional forces from air resistance and rolling resistance ( tyres ) .
What are two ways to increase air resistance of an object?
Increasing the surface area of the object, such as by adding flaps or a parachute, can increase air resistance. Additionally, increasing the object's speed will also increase the air resistance acting on it.
When a sheep first jumps out of a plane what happens to its speed?
The speed of the sheep will increase due to gravity pulling it towards the ground. As it falls, air resistance will also act on the sheep, ultimately causing it to reach a terminal velocity where the forces of gravity and air resistance balance out, resulting in a constant speed.
