What ways can a machine change a force to push or pull?
It can change by moving pushing or pulling you force it to
What are four ways forces can behave?
force's can change the speed, shape, size and direction of an object.
How useful are machine?
A machine saves you force, changes distance, and changes direction. Those are the three ways in science that why machines are useful.
What are ways in which force may change the motion of a body?
If a force is exerted on an object, it will accelerate in inverse proportion to its mass in the direction of the force. For example, if two objects of different mass are subjected to the same force, the less massive object will accelerate more.
What are two of the ways that the velocity of a car can change?
Change in direction change in speed
Describe the to ways in which velocity can change?
speed and direction
Two ways to change velocity?
speed and direction
In what three ways can accelerationchange an object's motion?
Acceleration is the change in velocity and/or direction of an object. Acceleration can either speed an object up, slow it down (deceleration), or change the direction in which the object is moving.
What two ways can a machine alter an input force?
1. Take a small input and you get a large force.
What are three ways that an object can be changed by a force?
by direction, speed and velocity i believe
Name a way to cause a change in velocity?
It can only be accelerated or decelerated, by adding to, or deleting from, the applied force causing the motion, or by increasing or decreasing the (opposing) frictional force. Acceleration includes starting. Deceleration includes stopping. Directional change may be imposed without causing a change in velocity, although practically, this change would be difficult to accomplish.
What are two ways that a force can change speed?
friction \
