How can you define force?
Force is an external effort in the form of push or pull, which tries to make the change in the motion/direction of the body. Forces are of two types balanced and unbalanced.
What two things does velocity tell about an objects motion?
speed and direction
Force that resists motion between two touching surfaces and always acts opposite to the direction of motion?
A force that resists motion between two touching surfaces and always acts opposite to the direction of motion is called friction. Friction will slow down a car when the brakes are applied.
When do two forces result in no motion?
Balanced forces do not result a change in motion. They are equal in size and opposite in direction.
What two conditions are necessary for uniform motion?
same speed. no change in direction
Four motion of the earth?
There are two different types of motions of the earth. Rotation is where the earth spins on its axis in a counter-clockwise direction. Revolution is the motion that causes the earth to revolve around the sun. It is also done in a counter-clockwise direction.
What are two types of star motions?
Actual motion and apparent motion.

In what two ways can velocity be changed?
Velocity changes when the direction of the motion changes.
What 3 terms are used to describe motion?
Two of the terms are speed and direction.
What two things velocity tell us about an object's motion?
speed and direction.
How can friction can help the cause of motion in certain situation?
The direction of friction is always opposite to the direction of relative motion of two bodies in contact.For example :in rolling motion of sphere the relative motion of the sphere (at the point of contact between sphere and ground)with respect ground is backwards, and hence friction acts in forward direction ,there by causing motion .
What are two velocity components of projectile motion?
The magnitude of its Velocity (Speed), and its Direction. These are the components of the Arrow (Vector) that represents its MOTION.
