What simple machine is the direction of effort opposite to the direction of resistance?
A pulley is a simple machine in which the direction of effort can be opposite to the direction of resistance. By using multiple pulleys and changing the direction of the rope, you can apply force in one direction to lift a load in the opposite direction.
What does a force in the opposite direction to the motion cause?
A force in the opposite direction to the motion of an object causes deceleration or slowing down of the object. This force acts against the initial motion, reducing the speed or changing the direction of the object.
The direction of kinetic friction is always?
against motion For example, if I push a box to the left, kinetic friction is going to the left.
What does a negative acceleration indicate about an object?
A negative acceleration indicates that the object is decreasing in speed or changing direction in the opposite direction of its current velocity. It could be slowing down, coming to a stop, or changing its movement trajectory.
What happens when velocity and acceleration are not in the same direction?
When velocity and acceleration are not in the same direction, the object's speed may be changing. If the acceleration and velocity are in opposite directions, the object will slow down. If they are at right angles to each other, the object will change direction without changing speed.

What is and opposite process?
An opposite process is one that reverses the original process, undoing its effects or changing its direction. It may involve taking steps in the opposite direction or using an action to counteract or negate the effects of the initial process.

A force in the opposite direction to the motion of an object causes deceleration or slowing down of the object. This force acts against the initial motion, reducing the speed or changing the direction of the object.

How can you tell if an object is accelerating?
You can tell if an object is accelerating if its speed is changing or if its direction of motion is changing. Acceleration is a vector quantity that includes both changes in speed and changes in direction.
Can acceleration ever be negative?
Acceleration is negative when the object is moving in the opposite direction. on a graph the line would be in the negative quadrant.
How can an object be accelerating if it's slowing down?
Acceleration doesn't mean "speeding up". It only means that the speed or direction of motion, or both, are changing. Speeding up is positive acceleration in the direction you're moving. Slowing down is negative acceleration in the direction you're moving, or positive acceleration in the opposite direction.
Is changing direction really the same as changing speed?
No. It is possible to change direction without changing speed. However, it is not possible to change direction without changing velocity.
What is any change in the speed or direction of a moving object called?
Any change in the speed or direction of a moving object is called acceleration. It can be caused by applying a force in the direction of motion (speeding up), opposite to the direction of motion (slowing down), or perpendicular to the direction of motion (changing direction).
How do rudders work to steer a boat in the desired direction?
Rudders work by changing the direction of the water flow around the boat, which in turn changes the boat's direction. When the rudder is turned, it creates a force that pushes the stern of the boat in the opposite direction, causing the boat to turn in the desired direction.
