Motion and Forces Review

Front

What is instantaneous speed?

Back

The speed of an object at a specific moment in time, as indicated by a speedometer.

Front

What is centripetal force?

Back

The force that acts on an object moving in a circular path, directed towards the center of the circle.

Front

How does weight change as you move farther from the center of the Earth?

Back

Your weight decreases as you get farther from the center of the Earth due to the reduction in gravitational force.

Front

What does the symbol 'p' represent in the equation p = mv?

Back

The symbol 'p' represents momentum, which is the product of an object's mass and its velocity.

Front

What is the path of a projectile?

Back

The path of a projectile is curved due to the influence of gravity and its initial velocity.

Front

Define average speed.

Back

Average speed is the total distance traveled divided by the total time taken.

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 gravitational force?

Back

The attractive force between two masses, which causes objects to be pulled towards each other.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the formula for calculating momentum?

Back

Momentum (p) is calculated using the formula p = mv, where m is mass and v is velocity.
