IS Fall Final Review Forces & Motion

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can occur due to a change in speed or direction.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity (P = mv). It is a vector quantity.

Front

What is the formula for calculating average speed?

Back

Average speed = Total distance / Total time.

Front

What force acts on an object in free fall?

Back

Gravity is the force that acts on an object in free fall, pulling it towards the Earth.

Front

What is circular motion?

Back

Circular motion is the motion of an object moving along a circular path, where the direction of the object is constantly changing.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as Weight = mass × gravity (W = mg).

Front

What is the role of friction in motion?

Back

Friction is a force that opposes the motion of an object, acting in the opposite direction to the movement.

Front

What is the difference between contact and non-contact forces?

Back

Contact forces require physical contact between objects (e.g., friction, tension), while non-contact forces act at a distance (e.g., gravity, magnetic force).
