What are the two properties of motion that can be changed to cause acceleration?

the two properties are: speed and direction.
speed: ex: you pass from 10 km/h to 20km/h. you have a delta v (=10km/h) and you have a time line during which the object is changing its velocity.
direction: the "velocity" seems to stay the same. ex: you travel with a car in a circle... even though u can see on the control board of the car that the car travels with 50 km/h, the car will accelaerate as the velocity depends on the displacement. and as u change the direction of the displacement ur velocity vector will change and therefore you will have an acceleration (centrifugal and centripetal forces will also play a role in the equation)

What can many other forces do that frictional forces cannot do?
cause motion &+ cause positive acceleration . #
Why don't you get motion sickness when you run?
our body can not feel velocity (without frame of reference) , it feels only acceleration. motion sickness is caused due to excessive acceleration, and as we know running can not cause an acceleration of that great magnitude so we can only get exhausted and not feel motion sickness.
How do balance forces acting on an object affect its motion?
When the forces acting on an object are balanced, they cancel each other out and the result is no change in its motion.Balanced forces have no effect on motion. Unbalanced forces cause acceleration.
Which is a more accurate statement that forces cause motion or that forces cause changes in motion?
This question is very unclear. Under the right circumstances any force will cause a change in motion. Whenever the net force, in a given direction, on a body is greater than zero, that body will move.
What causes a change in motion a balanced or unbalanced force?
Forces on a moving object are balanced only when the object is moving at a constant velocity. Remember, acceleration is a force and a constant velocity is equivalent to zero acceleration. Think of a ping pong ball that you drop from a few meters above the ground: After a short acceleration the ball reaches "terminal velocity" when the air resistance balances the gravitational acceleration. After this, the forces on the ball are balanced (although it is moving, the velocity - speed & direction - of the ball is not changing)
What changes in motion cause acceleration?
"Acceleration" is the term used to describe motion whose speed, or direction, or both, are changing.
When will a force cause motion?
A force will cause motion, specifically it causes acceleration, whenever it is unbalanced by an opposing force, such as friction.
What can other forces do that frictional forces cannot do?
cause motion &+ cause positive acceleration . #
What can many other forces do that frictional forces cannot do?
cause motion &+ cause positive acceleration . #
How will the unbalance force affects its motion?
It will cause acceleration in the direction of the net force.
Why don't you get motion sickness when you run?
our body can not feel velocity (without frame of reference) , it feels only acceleration. motion sickness is caused due to excessive acceleration, and as we know running can not cause an acceleration of that great magnitude so we can only get exhausted and not feel motion sickness.
What changes as a result of an applied force?
An unbalanced force will cause an acceleration and a change in motion.
What cause a person in circular motion to feel a push away from the direction of their acceleration?
Inertia
How does magnetic force cause motion?
Going back to basic physics, motion results from acceleration, and acceleration equals force divided by mass. The force exerted by magnetic fields is described by Coulomb's Law.
What will change if a force pushes an object in the same direction as the object's motion?
It will cause acceleration, and increase its velocity.
Does it take an increasing force to cause an increasing speed?
Yes. It is one of the laws of motion (the second law) that says that an object in motion will not change its motion unless acted on by and outside force. You'll have to add more foce to cause the object to speed up. Correction: No. The key word in the question is "increasing." A constant force will cause a constant rate of acceleration. Increasing force will cause an increasing rate of acceleration.
