Newton's Laws/Vocabulary

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity. It can involve speeding up, slowing down, or changing direction.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist a change in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a force.

Front

What does Newton's 2nd Law state?

Back

Newton's 2nd Law states that acceleration depends on two variables: the mass of the object and the amount of force applied to it.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion. Unbalanced forces cause a change in motion.

Front

What happens to a rollercoaster heading down a hill?

Back

A rollercoaster heading down a hill is accelerating due to the force of gravity acting on it.

Front

What is speed?

Back

Speed is the distance traveled per unit of time. It is a scalar quantity and does not include direction.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity. It is a vector quantity, meaning it has both magnitude and direction.

Front

What is force?

Back

Force is a push or pull on an object that can cause it to accelerate. It is measured in Newtons (N).

Front

What is gravity?

Back

Gravity is the force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = m × a, where F is force, m is mass, and a is acceleration.
