What would happen if a bowling ball collided with a standing pin?

What would happen if a bowling ball collided with a standing pin?

When the bowling ball collides with the pins, the momentum the ball loses is equal to the momentum the pins gain. An object’s inertia resists changes its motion. The momentum and force of a rolling ball is greater than that of the pins. This inertia of the ball will knock down the pins.

What keeps an object at rest and what keeps it moving?

Because of inertia, an object at rest rends to stay at rest. An object in motion tends to keep moving at a constant speed in a straight line.

What two variables are force dependent on?

Newton’s second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables – the net force acting upon the object and the mass of the object.

What two variables is acceleration dependent on quizlet?

The acceleration of an object increases with increased force, and decreases with increased mass. The acceleration is in the same direction as the net force. The acceleration of an object depends on what two things? The size of the force applied, and the mass of the object.

Does inertia depend on torque?

Equations. Angular acceleration is proportional to net torque and inversely proportional to rotational inertia.

What are the factors that affect the moment of inertia of an object?

Factors that affect the moment of inertia

• The density of the material.
• Shape and size of the body.
• Axis of rotation (distribution of mass relative to the axis)

Does greater moment of inertia mean faster?

Because the relationship of the moment of inertia to rotation is exactly analogous to that for inertia and motion, a body with a lower moment of inertia will rotate faster than a body with a higher moment of inertia, even if they have the same masses and sizes.

What are the three principal axes of rotation for the human body?

The three principal axes of rotation in the human body are the longitudinal axis, the transverse axis, and the medial axis. The three axes of rotation in the human body are at right angles to one another.

What is the relationship between the center of gravity and the support base?

What is the relationship between the center of gravity and the support base for an object that is in stable equilibrium? A vertical line through the center of gravity must pass through the support base.

Can a force produce a torque when there is no lever arm?

Can a force produce a torque when there is no lever arm? No because there needs to be a lever arm to produce torque.

Where should a force be applied on a lever arm to produce the most torque?

What is the lever arm of a force? It’s the perpendicular distance from line of force to the axis of rotation. In what direction should a force be applied to produce maximum torque? Perpendicular.

When you carry a heavy pail of water in your right arm Why do you tend to hold your left arm out horizontally away from your body?

When you carry a heavy load—such as a pail of water—with one arm, why do you tend to hold your free arm out horizontally? Answer: You tend to hold your free arm outstretched to shift the CG of your body away from the load so your combined CG will more easily be above the base of support.
