Force and Motion (Based on Amplify Science) Chapters 1-4

Front

What can cause a greater change in velocity? A stronger force, or a weaker force?

Back

A stronger force can cause a greater change in velocity.

Front

What does velocity mean?

Back

Velocity is the speed of something in a given direction.

Front

When two objects with different masses have the same exerted force when they collide, which object will have a greater change in velocity?

Back

The lighter object will have a greater change in velocity.

Front

When two objects collide and they have the same mass, what happens?

Back

The two objects move in the opposite direction with the same strength.

Front

What does force mean?

Back

Force is strength or energy as an attribute of physical action or movement.

Front

What is the relationship between mass and acceleration when a constant force is applied?

Back

As mass increases, acceleration decreases when a constant force is applied.

Front

What is Newton's second law of motion?

Back

Newton's second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

How does friction affect motion?

Back

Friction opposes the motion of objects, causing them to slow down or stop.

Front

What is the formula for calculating force?

Back

Force is calculated using the formula F = m * a, where F is force, m is mass, and a is acceleration.

Front

What is inertia?

Back

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