Can List 3 things forces can do?
Forces can cause an object to accelerate or decelerate, change an object's direction of motion, and deform an object by stretching or compressing it.
What are 3 things that forces can change?
Forces can change the speed of an object, the direction of an object's motion, and the shape of an object.
What are the 2 forces acting on a sinking object?
The two forces acting on a sinking object are gravity, pulling the object downward, and buoyancy, pushing the object upward. Buoyancy force is caused by the displaced fluid pushing back against the object's weight, resulting in the object sinking, floating, or rising depending on the balance between these forces.
What are the 3 things that can cause a change in acceleration?
Three things that can cause a change in acceleration are a change in the net force acting on an object, a change in the object's mass, or a change in the direction of the force acting on the object.
Two forces are acting on an object. one force is pulling 9 newtons to the left and the other is pulling 3 newtons to the right. what is the size and direction of the net force?
The net force acting on the object is 6 newtons to the left. This is calculated by subtracting the force pulling to the right (3N) from the force pulling to the left (9N).

How is net force on an object determined?
The net force on an object is determined by adding up all the individual forces acting on the object, taking into account both their magnitudes and directions. If the individual forces are in the same direction, they are added together. If they are in opposite directions, the forces are subtracted from each other. The resulting net force determines the object's acceleration according to Newton's second law of motion.
What is the net external force of an object?
How do you determine the net force on an object? Decide which direction is positive motion. Motion is the opposite direction is negative The forces must in a straight line!! Add all the forces in straight line acting on the object. Example To the right is positive A 5 N force pushes a 10 Kg object to the right. A 2 N force pushes the same 10 Kg object to the left. The 5 N forces is positive and the 2N force is negative Net force = +5 N - 2 N = + 3 N To determine the acceleration use Newton's 2nd law of motion F = Mass * acceleration + 3 N = 10 Kg * a a = 10 Kg ÷ + 3 N a = +3 ⅓ m/s^2 The positive sign means the object is accelerating to the right!! If the forces are not linear, you must use vectors, but the net force in any direction is still the sum of the vectors in that direction.
What best detirmines the net force when more than one force is acting on an object?
You need to get the vector sum. You can do this by resoving all forces into its 3 axis components, adding forces in like axes, and compute the new vector.
What are the 3 external forces in the Earth?
The 3 external forces acting on Earth are gravity from the Sun and Moon, solar radiation pressure, and tidal forces from the Moon and Sun.
Two forces are acting on an object. one force is pulling 9 newtons to the left and the other is pulling 3 newtons to the right. what is the size and direction of the net force?
The net force acting on the object is 6 newtons to the left. This is calculated by subtracting the force pulling to the right (3N) from the force pulling to the left (9N).
When finding net force why must you know the directions of the forces acting on an object?
In order to find the Net forces, you need to know the X, Y and Z component of the object since their vectors(unit of distance and direction) are used to calculate the magnitude and direction of the object.... for example, if an object moves 3m in the X-axis and 4m in the Y-axis, then the net distance is 5m with an angel of tan(@)=4/3... Thus we know the distance and direction of the object... This can also be used for velocity (m/s), accelerations(m/s^2), and jerk (m/s^3)... note, that an object will always have a Y component of 9.81m/s^2 (gravity)...
Which is an example of balanced forces acting on an object....... 1. a kangaroo jumping 2. a car turning a corner 3. a cyclist slowing down or 4. a leaf lying on the grass?
a car turning a corner
What is the minimum number of unequal vectors that give a zero resultant?
Three One is obviously out. Two is out because if two unequal forces n and p act on an object the resultant with the minimum force in magnitude is |n - p|, which will never be 0 if n =/= p. Three can be easily resolved with a quick example. Imagine an object with three concurrent forces acting on it. Two forces, n = 3 N and p = 4 N, create an angle with each other such that the resultant is 5 N. 180 degrees from the resultant, a force, r = 5 N, is acting on the object. Thus three unequal vectors on an object can result in 0.
