What is the direction of static friction acting on an object placed on a horizontal surface?
The direction of static friction acting on an object placed on a horizontal surface is opposite to the direction in which the object is trying to move.
Condition where tangential force is considered almost horizontal?
In the context of physics, when the tangential force acting on an object is almost horizontal, it means that the force is predominantly acting parallel to the surface of the object. This scenario often occurs when an object is moving along a horizontal surface and experiences frictional forces that oppose its motion. The horizontal component of the force is crucial for determining the object's acceleration and frictional interactions.
Why does the horizontal component of the speed not change values?
The horizontal component of velocity remains constant for an object in projectile motion because there are no horizontal forces acting on the object once it is in motion. In the absence of air resistance and other external forces, the object will continue to move horizontally at a constant speed.
Why ax equals 0 for projectile motion?
In projectile motion, the horizontal acceleration (ax) is equal to 0 because there are no external horizontal forces acting on the object once it is launched. This means that the object continues to move at a constant horizontal velocity throughout its trajectory.
What have horizontal and vertical velocities due to gravity and follow a curved path?
Horizontal velocity remains constant due to no horizontal force acting on the object, while vertical velocity changes as gravity accelerates the object downwards. The combination of horizontal and vertical velocities creates a curved path known as a projectile motion.
What is the direction of static friction acting on an object placed on a horizontal surface?
The direction of static friction acting on an object placed on a horizontal surface is opposite to the direction in which the object is trying to move.
What is the relationship between rolled distance and time taken?
If an object is rolling along a plane horizontal surface with no other forces acting on it, then rolled distance is directly proportional to the time taken.If an object is rolling along a plane horizontal surface with no other forces acting on it, then rolled distance is directly proportional to the time taken.If an object is rolling along a plane horizontal surface with no other forces acting on it, then rolled distance is directly proportional to the time taken.If an object is rolling along a plane horizontal surface with no other forces acting on it, then rolled distance is directly proportional to the time taken.

What is the amount of horizontal force required to start in motion an object sitting on a horizontal surface must be great than what?
The amount of horizontal force required to start in motion an object sitting on a horizontal surface must be greater than the force of static friction acting on the object. This is because the force of static friction opposes the applied force until the object starts moving.
What have horizontal and vertical velocities due to gravity and follow a curved path?
Horizontal velocity remains constant due to no horizontal force acting on the object, while vertical velocity changes as gravity accelerates the object downwards. The combination of horizontal and vertical velocities creates a curved path known as a projectile motion.
How are the horizontal motion and vertical motion related in physics?
In physics, horizontal motion and vertical motion are independent of each other. This means that the horizontal motion of an object does not affect its vertical motion, and vice versa. Each motion is determined by its own set of factors, such as velocity, acceleration, and forces acting on the object.
How does the unbalaced force of gravity affect the horizontal and vertical velocities of an object in projectile motion?
In projectile motion, the unbalanced force of gravity only affects the vertical velocity of the object. Gravity causes the object to accelerate downwards, increasing its vertical velocity while the horizontal velocity remains constant since there is no horizontal force acting on the object. The combination of the horizontal and vertical velocities determines the overall trajectory of the projectile.
What is the component of projectile motion is not influenced by gravity?
The horizontal component of projectile motion is not influenced by gravity. This means that the object will continue to move horizontally at a constant velocity, regardless of gravity acting on it.
What is the difference between free fall and projectile motion?
Free fall is the motion of an object falling under the influence of gravity alone, without any initial horizontal velocity. Projectile motion, on the other hand, involves both horizontal and vertical motion, with an initial horizontal velocity and the force of gravity acting on the object.
What are for an object projectile motion?
For an object in projectile motion, its path is a parabolic arc due to the combination of horizontal and vertical motion. The horizontal component remains constant and the vertical component is influenced by gravity, causing the object to follow a curved trajectory. Key parameters include the initial velocity, launch angle, and gravitational force acting on the object.
